Can confirm, at least the limited options I use, most works great on Galaxy Tab S8 Ultra (SM-X900) on BVK4 firmware.
Options I use:
Advanced Power Menu (all of the following I have enabled working) - Power Off, Restart, Download Mode, Screenshot, Screen Recorder, Flashlight
Unlock Keyguard Before Actions
Camera shutter sound menu
Fake system status official
Only thing of the options I use that didn't work was Secure flag disabling (tested with screenshotting Xfinity Account info which doesn't work unless secure flag disabled). Not even a big deal since I mostly use this option on my phone.
If I didn't list an option, I didn't test it. I would be more than happy to when I have time if anyone would like. Also keep in mind my tab is WiFi only, so I wouldn't even be able to test a good amount of the options anyway. The most important thing to me has always been the advanced power menu options and it works great!
One last note, APM hasn't worked on our Tab S7+ (SM-T970) in a long time. I never reported it and honestly since I now have the S8 Ultra, don't care much. It definitely used to, and I suspect it could have been a change in LSposed over changes in firefdskit or firmware. My wife still has S7+, but never really used it anyway. I'll wait for A13 to drop for S7+ and test again. No reason really to look into it at this point anyway imo.
Thanks
@firefds for one of the best Samsung modkits out there today!!

EDIT: I'm not one to usually ask for feature requests, but since there isn't even a severely nerfed GravityBox available for Android 13 anymore afaik, I figured I'd ask. The only remaining option I used in GB was hold back button to kill foreground app. And it actually worked on Samsung tabs up to Android 12L. Also mapped holding recents key to launch calculator, but that's no biggie.
Any chance this could be implemented into firefds kit? And/or does anybody know of another mod that can add this option that works with Samsung ROMs? (I know you can do this with Tasker, but I'm looking to do it without that overhead)
