Is there a way to block PO Box addresses from being entered during checkout?

Hi, our app enables native checkout validation (King Checkout Validation), which checks each field according to the rules you set yourself and prevents unexpected checkout, and shows the error message below the field.

for example:
Prevent Post office (PO) boxes address
Check if the address contains a house number / apartment number
Check if the number of field characters exceeds the maximum value
Customized keywords and regular expression checking rules

etc…
