Using iwlwifi during install

I'm trying to install FreeBSD 13.2. My laptop has an Intel 8260 Wireless-AC adapter. The live install media uses the "iwm" driver by default which does not work with this network adapter (no networks found). The "iwlwifi" driver works fine without issue when I set it up post install. How do I switch to this driver on the live install media prior to installation? The "kldload" command says the "iwlwifi" driver is already loaded alongside the "iwm" driver.
iwm does not seem to be builtin in GENERIC kernel, so you could try to stop it from loading automatically using the following from loader prompt:
set module_blacklist=iwm
