@ice9g PPT = "Platform Trust Technology visibility to the operating system" - An added layer of security protection. If you disabled Secure Boot in BIOS setup first, the PTT option may not be visible. So that may mean it's off.
@Tesla1856 - Good one! Forgot about changing RAID to AHCI...
I was able to install a number of other linux distros without issue, and since the error message (for me) involved EFI boot, I suspect the problem with installing Ubuntu Server on the XPS 8950 is something Canonical will need to resolve.
FWIW -- Fedora 37 Workstation and Server both install and run without issue (and seem to do what I need, allow access to the Intel UHD 770 through /dev/dri for hardware accelerated Emby/ffmpeg). The downside is that I suspect the pain of going through Fedora's new release upgrade process every year or so hasn't changed since the last time I used Fedora for something serious (15 or 16).

Can you please define what PTT is, I have disabled Secure Boot and removed windows boot manager in BIOS.

Do you have to disable PTT and Secure Boot, remove Windows Boot Manager from Boot Sequence, if listed, etc - all in BIOS setup?

Be sure BIOS is set to AHCI (not RAID).
Only one SSD connected for now. Should be completely blank. F12 on boot.

I was not able to resolve it, though Ubuntu desktop installs ( but doesn't work well, it freezes up)

I also have this problem (and it also affects Ubuntu server 22.10).
I've tried everything mentioned previously (and then some):
