How to lock a Mac lock screen without using keystrokes in the script?

I’d like to go to the Mac lock screen with a command line script. Many of the existing answers suggest something like osascript -e 'tell application "Finder" to sleep', but my computer does not allow me to change the settings to show the lock screen on sleep.

The AppleScript includes a command to open KeyboardCleaner which disables access to the keyboard and I’d like to run this while KeyboardCleaner is active. So any script/command that doesn’t depend on keystrokes is required.

I’ll run my AppleScript (which opens KeyboardCleaner and also locks the computer ) by running

python3 -c 'from file import *; script();'

This is what I’ve tried

1. osascript -e 'tell application "Finder" to sleep' – my computer does not show the lock screen on sleep.
2. alias afk="osascript -e 'tell application "System Events" to keystroke "q" using {command down,control down}'" – this requires using the keyboard which is not possible for my use case
3. pmset displaysleepnow – same problem as 1
4. tell application "System Events" to key code 12 using {control down, command down} – same problem as 2
