Ipad latency

Hey there ! So i am going to buy Steinberg ur22 mkii . I will use it with my pc and with my ipad sometimes. I wanted to ask a few questions .
Can you change buffer size in cubase LE on ipad ( ipad 2018 in my case ) . And how is the latency different from pc’s latency , because as far as i know on iOS does not provide ASIO drivers and it is impossible to install the ur22 mkii drivers on ipad .
