e85 in 20’ SQ5? Non-flex fuel rated?

I’ve been running e85 in my 2020 SQ5 for the last 4 months with an e85 tune from IE. I was wondering if I have to worry about any fuel line corrosion as it’s not technically a flex fuel vehicle, and should I be cleaning it out with 91 every so often?

This is another reason I hesitate buying a used car.
