Let me correct this comment (it's been a while)

I've avoided using -F (on the receive) with -RI (on the send), which is
what I'm guessing you are doing if it is removing snapshots "for you."

So: actually using -R (send), skipping -F (receive; no snapshot removal);
post-xfer expiration of backup-side snapshots.

Is the -u option of any use to you on the receive? You can receive it
initially with -u and then set a local mount point property...
