The kernel version of the device is installed as 6.1.80. I created an image by building openwrt 23.05 with kernel version 6.6.56, and attempted to upgrade using the image via luci. The booting was complete, but the network interface information disappeared, and when I checked, the version printed by uname -a was different from the version actually existing in /lib/modules/.
root@-:/# uname -a

Openwrt does not support changing the kernel.
As OpenWrt is built to support many hardware architectures and is low-level hardware driver oriented, the system requires 100+ hardware related kernel patches, both for general Linux and possibly for the specific CPU target.
If you try to do major kernel upgrade over several major Linux versions, you will likely need to modify lots of patches and also lots of supporting drivers/daemons.
To put shortly, very likely you will not succeed in your endeavour.
