Please refer https://askubuntu.com/help/on-topic, Ubuntu and official flavors of Ubuntu (https://ubuntu.com/download/flavours) are on-topic on this site. The on-topic link provides alternate SE sites for non-Ubuntu OSes. Official Ubuntu is on-topic here, you mention using a remix from raxda & not official Ubuntu; that is supported on SE Unix & Linux — guiverc, Nov 03 '22 at 05:41

This question is off topic but the answer applies to standard versions of Ubuntu as well.

Your output says that the service is disabled. In order for the service to start at boot, you will need to use systemd to enable the service.

Run the following command to enable the service:

sudo systemctl enable ssh

Once a service is enabled, it will automatically start at boot.

Conversely, you would disable a service to prevent it from starting at boot:

sudo systemctl disable ssh
