Yes. With wifi disabled in the BIOS, the laptop boots both with and without a card inserted.

Booting a recent GENERIC with the following /boot/loader.conf


uname -a: 

FreeBSD supernovo 14.0-CURRENT FreeBSD 14.0-CURRENT #0 main-n246598-30659d1dcbc:

Booting with card inserted, wifi enabled in BIOS succeeds.

Booting with no card inserted wifi enabled in BIOS fails.

Booting with a card insert wifi enabled in BIOS succeeds.

Booting with no card inserted with wifi disabled in BIOS succeeds

The dev.rtsx.0.inversion flag inverts the behaviour: With wifi enabled
booting fails with the card inserted and succeeds with no card inserted.
