Say, by sending some value to something inside /sys/.../cpu or the likes. I have already aggressively debloated the tablet, but I like to experiment and I am not afraid to destroy the tablet since I bought it for 150 bucks at sale. Or pehaps there is some Magisk module that can do this?
The tablet is a Samsung Galaxy A9+.


Cool! I had little to now knowledge on e-readers… Wanting to buy one, and realizing how expensive they are, is what made me go for the Galaxy Tab A9+. It was about 150 bucks, on sale. I don’t regret it.
I hope tweaking the scaling governor helps you some, but as I have stated in the various updates in the OP, it has its quirks…
