Or take tire off yourself and patch NOT PLUG from inside.

I've put an internal patch on multiple car & truck tires. This is the BEST way to permanently patch a tubeless tire, but it does take a bit more work.
I've also used the same type patches to patch bicycle and dirt-bike tubes MANY MANY times.
Just make sure you have a smooth & clean area where the patch is going.
I use a pneumatic sander to smooth out the patch area if the inside of the tire carcass has any ridges/grooves.
In fact, I only use plugs in an emergency. Which has been all of one time on a tubeless bike tire... it did work fine and held for 4K miles.
