Larger Lock-Screen PIN buttons? Problem:
I just upgraded my phone software, and the lock screen PIN buttons have changed appearance!  They are now shifted up, smaller (circular with spaces in between them, instead of square and using the whole screen area), and less responsive.  This seems like a terrible idea from a UX standpoint- completely messing up my muscle-memory; now every time I try to log in to my phone, I screw up the pin at least twice.  Very annoying.
Examples:
Before the lock-screen PIN had something like this, with square buttons, except they were larger &amp; took up the whole the middle of the lock screen:

Now, this is the awful new lock-screen PIN layout:

Phone Specs:

Galaxy S10e (SM-G970U)
Android Version 11
ONE UI version 3.0
New Software Version: G970USQU4FTLN / G970UOYN4FTLN / G970USQU4FTN

What I've tried:
When I try to look up this issue, most of the responses will be about changing my PIN lock-method to a password / pattern, etc. lock method, or changing the PIN itself.  Those Q&amp;A's I've found addressing the appearance / behavior of the lock screen tend to say it's inbuilt to the system &amp; nothing you can do except for really cracking your phone software.  I also don't see anything in Accessibility options, but maybe I'm missing something.  Any ideas, or is this really something I'm going to have to put up with (until I get mad enough &amp; just throw it in the trash)?
There are Apps in the Play Store that provide an alternative lockscreen. Have a look at this page to see some. But from a perspective of security, I would personally avoid using an alternative lockscreen app, as you give your whole security and privacy into the hands of one app. But that's a decision you should make on your own. Android itself does provide the functionality to let other apps handle such important things using Device Administrator rights.
Other workarounds would include using an alternative locking method like Smart Lock or installing another ROM, for example LineageOS.
I personally would try getting used to it.
