TPGs will do anything....... if you throw enough money at them. Worth a phone call to ask.

NGC will slab a proof set in a single holder. Not sure if the others do.
Years ago NGC customer service told me they would only slab a large lot of proof sets, not a single set. I’ll contact them again.
Certainly no downside in 'asking/confirming', but it looks like the NGC policy has not changed:
