Depending on the Switch in question (I.e. is it a V1 switch) you can soft mod it - firmware level doesn’t matter). The first thing you should do is check your serial number with a tool like https://ismyswitchpatched.com/ . If that comes back with “Your console is not patched. Hooray!” then your switch is soft mod compatible. If your switch is not compatible then you are stuck with a mod chip most likely.
