Can I drive without an MAF sensor?

2017 Sienna XLE.

I have a 600 mile road trip ahead of me back home tomorrow. CEL came on, I went to AutoZone and the guy said the codes mean it's an MAF problem (lean on some cylinders I think but I don't remember the codes). They sold me a new sensor but it didn't fit, they didn't have the right one in stock. Tried MAF cleaner on the old one and, the CEL is still on after driving around for 20 minutes.

Is it fine to drive home with the faulty sensor plugged in, should I unplug it, or should I try every auto parts store on the way home and see who has mine in stock?

What happens if I unplug it and leave it unplugged?
