Yes, and if you boot from the USB installer and don't see that, then something is wrong on the USB installer. And when you boot from the USB installer, you can use the DU on that screen to reformat the partition that is APFS to clear it out for the installation.
But you haven't actually said you booted from the USB installer, just that you "plugged in" the installer. You would need to boot from the installer to get to where you get that screen you posted.Jake

I alway get the Disk Utility option with any Mac OS X/OS X/macOS bootable USB installer I have created, going all the way back to Mac OS X Lion (10.7). You should create a new bootable macOS USB installer.-- Bob --

I spent a bit of the Canadian Thanksgiving to repeat my first Mojave installation.
kept a written record step-by-step, it went like this:
Into the Mini running 10.11.6, I plugged in an external USB 3.0 drive with two ElCapitan (10.11.6) backups on it - each one on a separate partition of that external drive.
Both backups show on desktop
Launch 10.11.6 Disk Utility to erase one of the two backups.
Choice of formatting are the various OS X Extended versions plus MS DOS and ExFAT; I chose OS X Extended (journaled)
Complete the Erase process of the one external partition.
Then I plug the Mojave USB installer into a USB 3.0 port of the Mini
Installer shows up on the desktop.
I launch the installer and get the first image I have attached - no Disk Utility option anywhere. On older installers there used to be a drop down which included Disk Utility, but not here - I double checked them all.
Then I just kept following the prompts, agreed to the license, selected the "Mojave Test" partition (which was the erased OS X Extended format.
Next I needed to enter my admin credentials for the Mini so that a "Helper Tool" could be installed (see attachment) and then Mojave was installed completely.
Definitely no formatting to APFS at any point
(Next test will be a separate post to keep the attachments correctly associated

So I went and did that, and sure enough, disk utility showed up as an option almost immediately so that I could erase the Mojave with the wrong User data on it.
Just shows you that I haven't done a clean install for a long time.
The purpose of the Mojave exercise was actually just a test to see if the "Save As..." permanent fix works with that OS - haven't gotten to that point yet.
I'll transfer the correct User data to Mojave tonight and take it from there

I wouldn't be at all surprised that Mojave with a long with Apple's management paranoia about security prevents you from doing so, at least not without disabling SIP to attempt the change.
But I'll stay tuned in...
BTW: Happy Canadian Thanksgiving and I hope you didn't drain all the eggnog.

I thought this would be an easy check on Mojave to see if the "Save As..." fix (so to speak) works, ie make "Save As..." a permanent option under the menu.
Well it turns out after I ran Migration Assistant on the Mojave install I did on the external partition where I installed Mojave after booting the Mini in Mojave using the USB installer, the Mini won't boot up on anything when I hold down the option key.
I tried restart first, then I tried shutting down the Mini, starting it by pushing the power button momentarily and the holding down the option key - the Mini light comes on but otherwise nothing.
I tried booting the Mini without the USB 3.0 external plugged in - works fine.
Then I tried booting up the Mini with the USB 3.0 external plugged it (not holding down the option key) - Mini boots into ElCapitan, works fine, the partitions on the Mini that are not APFS show up as expected.
Then tried it again with the external plugged in and holding down the option key (I used to get the Mac HD, the two ElCapitan backups, the partition with the installed Mojave OS and the Mojave installer before - now I get nothing.
Haven't had time today to play with this some more, just makes no sense to me that starting up and holding down the option key brings up absolutely nothing (after I ran Migration Assistent over night)
