Raspberry PI firmware upgraded no Home Assistant boot anymore

Home assistant indicated there is a Raspberry PI Firmware uprgade, see screenshot.

After the upgrade the platform rebooted but home assistant never came back. After connecting a montior to the raspberry pi I discovered it is booted with the Raspberry PI Desktop!!

Somehow the boot order has changed. How can I get this back so that it boots my Home Assistant again?

I'm using a Raspbery PI V5 with a SSD connected via NVMe.

I found the Home Assistant partition with the lsblk command:

It is the "nvme0n1" partition on which HA is installed. how can I select this partition to boot from?

Found the solution, using sudo raspi-config it is possible to change the boot order. I've my HA back again, ppppfffff

Still q question, why would you upgrade the following:

And how to prevent I'm running into the same situation if i upgrade from within HA>
