I've come up with K&N: 33-5086 but not sure if it'll be a match. They do not have any data or information.

Well, outside of waiting for an official release for the X7 50i/M50i, I think using the cross reference filter element info from other BMW models will be your best bet since all that really matters is that the new drop in filter will physically fit inside the factory air box. That said, I would not personally use a K&N filter - not a fan of them. FWIW, I have a set of AFE Pro 5R drop in filters in my M3 (BMC is also popular on the M3/M4 forums).
It looks like BMC has an option for the X7 50i.....
