I’d suggest unplugging the fingerprint reader / power button until support gets back to you.
You can use the “Power on AC attach” option in BIOS in the meantime. And the power button on the motherboard to power-on, so you can get into the BIOS.
Be aware that it might take longer than normal for support to get back to you.
The Framework Laptop 16 release has seen a huge demand, unexpectedly so, and customer questions and order modification requests are putting a big strain on support resources.
