How do i disable driver updates? is this a AMD setting ?

Iam using 17.1 driver and it did not update itself, but i did notice before i adjusted any underclock or volt, that the core clock was not even hitting the stock setting in GPU-Z , Now once i undervolted the core clock went up to stock range in gpu-z and then if i lower the clock, it will lower the hashrate by 1.5 MH/s

Does this sound like i just need to DDU and reinstall blockchain drivers ?
