Any currently available GSI or AOSP for Galaxy Tab A7 Lite?

The ones on XDA have dead links or have no workable instructions. Anyone have a complete repository with proper insructions? My T220 was very affordable but honestly, it's brutally slow. OneUI is too heavy for these resources. I don't want Lineage, since it does not allow moving apps to SD.

A solid generic Android with Root would be just ((((chef's kiss)))).

The device already has Developer options set to allow OEM unlocking and I have adb etc. on PC.

I hope someone has something good for me. Thanks.
