Assuming you are in the US or Canada, very easy to be done and professionally. There are several hundred UbreakiFix franchises around which are Samsung authorized and they will be able to replace the battery with an OEM one in a matter of a couple of hours (just drop it off).
In Montreal I dropped off a Note 5 at one of their stores and a few hours later picked it up with no hint of the phone being pried open. Total cost C$115 or so (under US$100). Cannot recommend highly enough.
Edit: Just checking and for the Note 10 plus you will have to contact the store for a quote but I do not see a massive divergence from the indicated pricing I gave. If this job were done in Canada with a Note 10 plus the cost would be circa US$125 or so. Good deal.
