85,000 FNA Certificate question

I have an 85,000 point certificate from Bonvoy Brilliant card and am looking to book a room that is 101,000 points, just past the 15,000 top up limit.

Has anybody had success calling Marriott for an exception to this rule ?

Tried the other day and was stuck on hold , so figured would ask if there is a chance and if someone has done it, any words of wisdom to say to the agent

Thanks !
