Windows 10 Help with remote connection management

Hi,

I need to allow someone to remotely connect to my windows 10 desktop, and am wondering if this is possible:

I have a dual desktop monitor setup that is extended (not mirrored), and am wondering is it possible to grant someone remote access only to the secondary monitor?

I would like to work on the primary while he works on the secondary remotely.

Please advise if possible and if so how to set it up.

Thanks!
