Module still part of kernel after removing from conf file

[sham1810]

I'm trying to debug an issue with eMMC controller and would like to exclude the module (sdhci_acpi) from kernel and be able to load it myself when I make changes to the driver source. However, even after I commented these lines from the conf file, the module still shows up as a part of the kernel.

device mmc
device mmcsd
device sdhci_acpi

After removing these lines I run the following commands

make -j16 buildkernel
make installkernel INSTKERNDIR=freebsd12_dev

After rebooting with the new kernel, it still contains sdhci_acpi module as a part of kernel (checked using kldstat -v)

Any idea, what the problem could be?
I'm new to FreeBSD, any other advice on how to tackle device driver debugging is most welcome.

I have looked into other ways of excluding kernel module (WITHOUT_MODULE variable), but I'm curious as to why this does not work.

Never, ever, modify GENERIC. When people see your uname(1) output they are going to assume it's a standard GENERIC kernel, not a custom kernel. Rename the custom kernel and make sure to change the ident line accordingly.

Noted. I compiled it again with a new KERNCONFIG. It works.
