I want to disable the sign in screen on screen wakeup

Sounds like Windows is still requiring a sign-in due to a security setting, even if you don’t have a password set. One thing that worked for me is going to "Settings > Accounts > Sign-in options" and making sure "Require sign-in" is set to "Never." If that doesn’t work, you can also try turning off the lock screen feature entirely via Group Policy Editor or Registry Editor. That should stop the sign-in screen from appearing when waking up the computer.

Hope it helps!
