Possible to change controls for assigned skills ?

After playing Nioh 2 for 500+ hours I'm having trouble getting accustomed to some controls like holding Y for night rain instead of R1 + O like a classic iai or moving the analog stick and pressing Y for severing spin instead of pressing LB and Y or X

Is there a possibility of customizing those controls ? I spent some time in the menu and couldn't find it

I'd like to get back to Nioh 2 at some point and would like to avoid unlearning Nioh 2 controls and then relearning them back

Much appreciated !
