For some reason I installed a driver long time ago and it is no longer in use, and in root permission I checked the dkms status it shows this: enter image description here

I tried to removed it by using the following commands (separately)

 dkms uninstall -k rtl88x2bu -v 5.2.4.4
 dkms uninstall -m rtl88x2bu -v 5.2.4.4
 dkms remove -k rtl88x2bu -v 5.2.4.4
 dkms remove -m rtl88x2bu -v 5.2.4.4

So I wonder how to remove the added driver.

    Since the 5.2.4.4 version is not installed, you should be able to just remove the files from /usr/src.

    I removed it, but when I checked the 'dkms status' it's still there.

    See manpages.ubuntu.com/manpages/xenial/man8/dkms.8.html . I believe the command to remove that module would be dkms remove rtl88x2bu/5.2.4.4 --all

See: http://manpages.ubuntu.com/manpages/xenial/man8/dkms.8.html

In the link it is stated:

   remove [module/module-version] [-k kernel/arch] [--all]

       Removes  a module/version or module/version/kernel/arch combination from the tree.  If
       the module is currently installed, it first uninstalls  it  and  if  applicable,  will
       replace  it  with  its  original_module.   Use the --all option in order to remove all
       instances for every kernel at once.

Since the module you want to remove doesn't have a kernel associated with it the command to remove it would be:

dkms remove rtl88x2bu/5.2.4.4 --all

Where you only need to specify the module/version then --all to remove module completely from the system.
