can i disable two stage authentication
No.
See the full description at Two-factor authentication for Apple ID
In that support document Apple gives the system requirement for Apple TV as Apple TV HD with tvOS (as the minimum).
You did not say which model Apple TV you have but I suspect it is an early model. The last two models, the Apple TV HD and the 4K can respond to Two Factor Authentication requests but the earlier models require you to enter the 6 digit TFA code in the password field immediately after your password - for example abcde654321
Even then occasionally I had difficulty with Two Factor Authentication on my 2nd generation Apple TV before I replaced it with a new model.
