I faced a similar problem. You will note in mkimg.base.sh there is a =
line in section_kernels()

```
_pkgs=3D"linux-$_f linux-firmware wireless-regdb $modloop_addons"
```

This forces the linux-firmware to be available while building the =
modloop.
Putting the following into my mkimg.customiso.sh did the trick to remove =
them, leaving the build process untouched for other standard builds:

```
section_kernels() {
	local _f _a _pkgs
	for _f in $kernel_flavors; do
		_pkgs=3D"linux-$_f wireless-regdb $modloop_addons"
		for _a in $kernel_addons; do
			_pkgs=3D"$_pkgs $_a-$_f"
		done
		local id=3D$( (echo "$initfs_features::$_hostkeys" ; apk =
fetch --root "$APKROOT" --simulate alpine-base $_pkgs | sort) | =
checksum)
		build_section kernel $ARCH $_f $id $_pkgs
	done
}
```
Hope this helps.

Best,
