Possible issue found in 1.3, maybe this could be checked it's not only myself?
Bluetooth can't be disabled or enabled from the battery menu. The toggle moves but it doesn't work and stays in the same state.
I use this regularly as a quick way to achieve some power savings from one place, part of discussions on usage here
Disabling from there own respective pull down works correctly.

It also happens on my FP4 with 1.3

@Linus67 Why do you want to prevent background suspension? I think for your use case it would be better leaving it off, it uses less battery.
