mind this:
https://learn.microsoft.com/en-us/defender-endpoint/linux-exclusions#supported-exclusion-scopes
and work from these examples (if you're allowed to):

"Be glad it only slows your database down. All too often, AV/Endpoint
Protection Products just don't like the access pattern and eat your
database for breakfast." There is this joke "it has been 0 days since
Anti-Virus ate a database".
Things must have improved, since we had Carbon Black for a number of years, and now use Coretex XDR.
CB would quite often consume 300% CPU, while XDR "only" uses 100% on occasion, but have never corrupted or crashed a PG instance. (This is standard installations, with no exclusions.)
