If you are running quick scans, this should honestly not slow down the pc very much, as it generally finishes very quickly (at least if you have SSD drives).

https://docs.microsoft.com/en-us/microsoft-365/security/defender-endpoint/schedule-antivirus-scans?v...

If even this is difficult, I suppose you could disable the scheduled scans altogether, but scheduling them for the lunch break, or over night if circumstances allow it, would be better in my opinion.

You can't specify a time interval where scans will not start, but by default scheduled scans do not start while the pc is being used unless you have changed the default settings there.
