S8 | S8 Plus >> Hide the Lockscreen Clock completely?

[movESP0isgood]

• Goal: The goal is that the lockscreen DOES NOT display the clock (or anything from bottom to up except statusbar).
• Progress: I've managed to turn off notifications and roaming clock on the lockscreen but so far no progress on hiding the clock itself.
• Device Info: Running Pie on a DBT/No carrier S8+ without root. Substratum worked for me on Nougat but since then the app went into downhill after they started selling andromeda or whatever that cashgrab is and a useless 'samsung addon key' which btw I had to buy and couldn't use... thanks substratum...

I've seen people using ADB to enable 'immersive mode' though that only hides the navigations bar (which is already disabled for me) and the statusbar (which is not the goal).
Any other ADB command to do this?

The use of any launcher or lockscreen app is out of the question

Does Good Lock count as a lockscreen app to you? You can customize the existing one (using the LockStar plugin).
