Post [Q] Project Facelock

Hey,
Ive Been Using Facelock By Google And Ive Realised That The Preview On The Lockscreen Is A Bit Annoying So I Came Up With an Idea To Remove The Preview And Only Keep The Dots At The Same Time Keeping The Facelock Working...
Can Someone Please Help Me With This?
I Thought Of Editing The Layout In Framework But Dont KNow How To Start
