Update:
Ubuntu Server 22.04 LTS Kernel 5.17.5-generic
Changed
- Kernel 5.17.5
- Kernel based on original Ubuntu server build config 5.15.0 – generic. (Included all modules and boot time increased by 2 times. From 30 sec to 78 sec on a class 10 sd card.)
- ESP & boot partitions reduced.
- removed cloud-initramfs-copymods
SSH login\password

Also you can install kernel severally
I think in the future we can find good set of modules for avoid long time of boot. Generic kernel is redundant functions.
