Debian 12 image for IndieDroid Nova, low /boot partition, after single kernel update?

Debian 12 image for IndieDroid Nova, low /boot partition, after single kernel update? I removed the older 5.x kernel, but the /boot partition is still over 70% full and this impacts kernel updates and initfs updates. How can this /boot partition be resized? Not on a live system? Will need to boot from Micro SD card, if OS is on EMMC module right?

The default image for Debian 12 should be more like 512MB rather than 240 MB as it is now, IMHO.

More details…

Seems the /boot partition space issue appears only after attempt to install qemu/kvm. Once initramfs-tools is loaded, as part of qemu/kvm install, kernel 6.1.x is attempted to be enabled/installed. Still testing.
