Third party screen reticle and joystick, are they allowed in bf6

Title gives you the basics of this. Can I used a third party reticle from the Microsoft store in bf6 or will it be picked up by EAanti as like some sort of cheat overlay? I play a pretty high sense and loosing hipfire fights cause my eye can’t easily find center with this tiny center dot we have currently compared to other titles. Also there is a ‘joystick’ vehicle option which I don’t think works right now. When that comes online are we able to switch from controller (infantry) to tank/heli (joystick)? Like is that how it’s intended to be used? Haven’t used a joystick since my childhood might buy one if that’s the case just for the lols

i’d like to have the clearest possible answer here. Please don’t respond if your input is like a guess. I take competitive play pretty seriously and don’t wanna get banned down the line for trying these. Thanks!
