You might be able to have them center the big ring on the cassette, if they have the room on the inside. This will kind of give you a 1x with a granny just for those times you need it... if that is how you ride. I’m assuming it is since you were in the big-big.
I will admit that if you lined up the big ring with the center of the cassette and took off the inner ring, there would be those that would say it’s 1x so you’re not cross chaining. But put that small ring back on and the big-big is now cross chaining.
