Restoring the firmware from the testing firmware

I have a Samsung Galaxy A53 5G but its firmware version isn't the firmware it should have; it seems to be for device testing purposes. The phone runs the android and OneUI versions the A53 initially came out with and functions properly for the most part. There are apps technicians use such as "memlogger controller" "sdmhidden-menu" and "smart epdg test" that I can't uninstall, updates aren't supported with this firmware version and command lines appear on the screen during startup and shutdown. How can I fix this? How can I reinstall the original firmware so this phone is like a normal Galaxy A53 5G? The attachments show the apps and the firmware versions and some of the command threads.

@jayeff Can you please help me determine what the correct firmware is? My a53 phone model is SM-A536U1, it's the US version and is carrier unlocked. Which one should I download? There are numerous available. What product code is correct? United States DSA is an option I saw. Thank you.

Will I be able to recieve updates as I should? Also will this root the device?

@dwzzzz

If it is back to the original firmware then you should get updates up until 2027 when support for the phone is stopped by Samsung.

It shouldn't root the device as it is the original firmware.

Since it's unlocked, try a "USA" only (no carrier) firmware from here

Probably try the one with the latest date i.e. 25-01-22 and check.

You'll notice that all the major carriers use the same PDA for that date.

As the firmware date gets older down the page, the PDA changes.
