How to change to Assisted mode?

Sorry if this is a stupid question but I haven’t been able to find the answer by googling!

I bought RE4 for the switch today, started playing it, and discovered it is very difficult and awkward control wise for me. (I don’t play very many video games tbh)

Is there a way to change the difficulty setting on Switch? I don’t mind if it means starting again, I have only made it to the first village

Thank you!
