This laptop model have special TPM/Security chip, every time when laptop start, this chip will check special RSA signature.
When the BIOS integrity test fails, a sequence of 5 whistles is issued twice at boot.
After modifying to remove whitelist (enable unauthorized WI-FI cards), enable advanced menu, etc. the BIOS can't pass the integrity test (because bios was modified), and therefore sequence of 5 whistles is issued twice at boot.

In this case, I know only this ways (sometime it's can help, but sometime no) :

Pull out CMOS battery and wait 5-10 min to reset NVRAM data.

Set (in bios setup menu) TPM to Inactive (not to Disabled) after flashing.

Set (in bios setup menu) Security chip to Disabled.

Set Intel AMT module (in bios setup menu) to Disabled.

Set Anti Theft Module to Disabled.

Set Computrace (in bios setup menu) to Permanent disabled.
