Setting Driver for the Input Device after Driver installation without restarting an Operating System.

The Operating System:

ubuntu@ubuntu:~$  lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.1 LTS
Release:	18.04
Codename:	bionic

I kind of having struggle with restarting every computer for the configurations in the files (/etc/X11/xorg.conf.d) to be applied and kept wondering if there is any way to do that.

The important example of configuration that I would like to apply while X server is running:

Section "InputClass"
            Identifier "SynPS/2 Synaptics TouchPad reconfiguration"

            # Enable Synaptics Driver insted of libinput Driver
            Driver "synaptics"
EndSection

This bit of Configuration enables Synaptics Driver for a Touchpad that was recently installed.
