I think you confuse security and privacy. Samsung are pretty secure from what I saw. They are not private at all however. You can debloat it with adb and maybe tools such as Universal Android Debloater.
There is a couple of guide such as this one: https://linustechtips.com/topic/1402380-ultimate-samsung-oneui-debloat-privacy-customization-guide/
Use ADB to remove Google and Samsung bloatware and tracking. Ask around for help.
You should be able to use Heimdall to unlock the bootloader, but there isn't currently a build of LineageOS or DivestOS for this phone, so unfortunately you cannot yet flash a custom ROM (AFAIK). However, rooting should work if you need this (although it can hurt your security a bit).
I'd recommend removing Google Play Services and replacing it with microG, although this may be complicated.
The best solution, however, is probably to exchange the phone for a more versatile model, such as a Google Pixel or a Fairphone.
While many devices don't have ROMs built for them, any recent device should work with a GSI.
I just bought a tab s8, as I know Andy yan's LineageOS 20 works on it from other users' reports. I currently use it on my old tab 10.8 2019.
