Check kernel features

Kernel config is usually placed at /boot/config-$(uname -r) or /boot/config-$(uname -r)*

cat /boot/config-$(uname -r)*

grep -i search_keyword /boot/config-$(uname -r)*

If config file is not located in /boot, try

find / -name *$(uname -r)* orfind / -name *kernel*

Look at the path located by the find command and you may find a supurse.
