Because I still see a lot of people using value "0" on their scan policy; here's my method to get the proper value:
( Resulting in less crowded options in the Bootpicker )
Let’s say your config has Windows (NTFS) & MacOS (APFS) on Satas & NVMe Drives, but you’d also like to scan your USB for OS Installation purpose.
1- Enter your Calculator in MacOS ( to enter Programmer mode press: CMD+3 )
this window will appear:

2- Without entering any numeric values, click on the desired binary value ( in front of the red arrow ) to switch it from 0 to 1 ( 0= False / 1=True )
By doing so the big Hex value will appear:

Now we have:
FSL + DL+ APFS+NTFS+SATA+SAS/Mac NVMe +NVMe+USB. = 0x2B0903
0 + 1 + 8 + 11 + 16 + 17 + 19 + 21 = 0x2B0903
( Note that if the ESP Value = 0 ( Bit10 ) no EFIs will be scanned.)
3- Converting that HEX value to Decimal ( Any Hex Converter will do )
0x2B0903 -> 2820355
Your New Scan Policy is now:
2820355
Done!
