The driver would be "rtw88", not "re", for the card per ...

... as I understood, your Realtek WiFi card is in the state
of getting proper support, development is on going. I got the
impression that the card would be usable for unknown length of
time. If it would stop to work & would require a reboot, I would
not be surprised.

Whatever the state of current driver is, is not available from
13.[0]1-RELEASE images; 12.x-RELEASE might not ever get the support.

To test and/or use those changes, you would have to compile and
install FreeBSD from source. Source is available via Git repository;
need to use either "stable/13" (13-STABLE) or "main" (14-CURRENT)
branch.

For background and details to compile the OS, including the kernel,
