Hi,
ever thought of using the source from kernel.org? e.g. longterm:     5.10.191.

I use some script like this (untested) to compile it:

#! /bin/sh
arch=x86_64
SRCDIR=YOURDIR
cd $SRCDIR
CONFIG="/path/to/config.yours"
cp -f $CONFIG "$SRCDIR/.config"
echo "REMOVE CONFIG_SYSTEM_TRUSTED_KEYS"
./scripts/config --set-val CONFIG_SYSTEM_TRUSTED_KEYS \"\"
echo "REMOVE CONFIG_DEBUG_INFO"
./scripts/config --set-val CONFIG_DEBUG_INFO n
grep CONFIG_SYSTEM_TRUSTED_KEYS .config
make oldconfig

# add the configs you need
./scripts/config --set-val CONFIG_THAT_YOU_NEED y
make oldconfig

make -j4 bindeb-pkg LOCALVERSION=-custom

the result will be 3 debs that you can install e.g.:

linux-headers-5.10.191-custom_5.10.191-custom-53_amd64.deb
linux-image-5.10.191-custom_5.10.191-custom-53_amd64.deb
linux-libc-dev_5.10.191-custom-53_amd64.deb

Hope this helps.
Ciao,
Tito
