Wired Ring Doorbell (Pro/Pro2) Wall Mount for older houses with doorbell connected to recessed electrical/outlet boxes

My current doorbell is very old and the plate for it screws into a wall box like those used for outlets and light switches. The space between screws being 3.7 inches. If I remove the plate, there is a big ugly hole. I need a wall mount for my Wired Ring Doorbell (Pro/Pro2) that will screw into that wall box and cover that hole. I would drill new holes, but I have an HOA. Carlon 1-Gang 18 cu. in. Blue PVC New Work Electrical Switch and Outlet Box B118A - The Home Depot I've searches Ring, Amazon, and Etsy for a solution, but all the "old school" adapters don't fit. Anybody have any ideas? Ring please make this adapter, my community would thank you.
