Unfortunately, I don’t think so. Maybe I’m doing something wrong while flashing?
I tried two ways:
adb push ./TabS2/e-3.1.1-t-20251018-UNOFFICIAL-gts210velte.zip /storage/
after install in twrp
and
adb sideload ./TabS2/e-3.1.1-t-20251018-UNOFFICIAL-gts210velte.zip

Unfortunately I have the same issu of Jorkus. Same tablet model
Might be related to my build environment… will set up a new one when /e/OS-T 3.2 is available and I find some time to apply LOS-UL patch onto it
Camera is crashing, TARGET_PROCESS_SDK_VERSION_OVERRIDE overrides cameraserver target version to 23 to fix issues. I think TARGET_PROCESS_SDK_VERSION_OVERRIDE was removed after repo sync. (E os manifest replaces with their repos, not LOS UL repos)
If it may help, I tried with 2.7, 2.9 and the 3.1 you released on April and, apart from the 90° rotation problems, it starts and worked “well”. Really difficult to setup, but finally I saw the home screen. The last release, you posted days ago, just starved on eOS logo, rotation problems seems solved due to the logo sreen starts on vertical, not orizontal side like the others 3. I don’t know if it’s releated to your environemnt, because April 3.1 release didn’t have this “starving” problem. Always thank you so much for your help!
As said might be related to my build environment… will set up a new one when /e/OS-T 3.2 is available and I find some time to apply LOS-UL patch onto it
One last try before I setup my new build environment
Great, it works, Thank You (e-3.1.1-t-20251020-UNOFFICIAL-gts210velte.zip)
Great! Then it was my build environment. Does rotation problem exists? How about LTE?
It’s ok, no rotation problem,
camera don’t work
location/GPS don’t work - I checked the maps
LTE -I don’t know yet
location/GPS works - I needed to go outside 
LTE - doesn’t read the card, no card but card inside
Can you provide logcat?
Yes, but unfortunately tomorrow
please see here:

Camera and a lot of other things do not work
You can even test A14 version:
However its untested yet and might not boot
I’m attaching the logcat, maybe it will help
Is this for the A14 version or A13?
this is for A13
I tested a14 : rotation come back, don’t start, no logcat : - waiting for device -
Bluetooth does not work, checked in logcat
Crash loop, can cause battery draining
