1. First, we need to find the touchpad and keyboard's id.

❯ xinput list
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ OBINS OBINS
AnnePro2 Mouse              	id=13	[slave  pointer  (2)]
⎜   ↳ YICHIP Wireless Device Mouse            	id=14	[slave  pointer  (2)]
⎜   ↳ YICHIP Wireless Device Consumer Control 	id=16	[slave  pointer  (2)]
⎜   ↳ SYNA3073:00 06CB:8265 Mouse             	id=17	[slave  pointer  (2)]
⎜   ↳ SYNA3073:00 06CB:8265 Touchpad          	id=18	[slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad              	id=20	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Video Bus                               	id=7	[slave  keyboard (3)]
    ↳ Video Bus                               	id=8	[slave  keyboard (3)]
    ↳ Sleep Button                            	id=9	[slave  keyboard (3)]
    ↳ OBINS OBINS
AnnePro2                    	id=10	[slave  keyboard (3)]
    ↳ OBINS OBINS
AnnePro2 Consumer Control   	id=11	[slave  keyboard (3)]
    ↳ OBINS OBINS
AnnePro2 Keyboard           	id=12	[slave  keyboard (3)]
    ↳ YICHIP Wireless Device System Control   	id=15	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=19	[slave  keyboard (3)]
    ↳ HP WMI hotkeys                          	id=21	[slave  keyboard (3)]
    ↳ YICHIP Wireless Device Consumer Control 	id=22	[slave  keyboard (3)]

In the command output above, the SYNA3073:00 06CB:8265 Touchpad id=18 is the touchpad, and the AT Translated Set 2 keyboard id=19 is the keyboard.

2. Then, we use the command below to disable:

# Disable the touchpad
xinput disable 18
# Disable the keyboard
xinput disable 19

3. If we want to re-enable, just use xinput enable {id}.
