I tried something similar, but am having mixed results. I added 
"buster-proposed-updates main" to sources.list, and installed 
linux-image-4.19.0-10-amd64. Which I think should be the same as Aaron Lu 
retrieved, except I have the signed variant. I installed on a Panasonic 
CF-19 laptop running Debian 10.4 and xfce.

Recovering from screen blanking and locking does work with that version of 
the kernel. So, on my computer, it does work better than the standard 
buster kernel 4.19.0-9. However, suspend and hibernate still don't work. 
I haven't had a chance to try Aaron Lu's suggestion of backported kernel 
5.6.0. However, I have been using 5.4.0 for a while, and blanking, 
locking, suspend, and hibernate all work with that version.

Hope this information is helpful.
