Should I flash pure AOSP in my SM-A207F (Galaxy A20s) phone?

Hi all, I’m a newbie to phone flashing and stuff like that, but I’m not new to phones. So I want to flash pure AOSP in my Galaxy phone. Turns out when I unlocked the bootloader of the phone and was 'bout to start flashing the ROM in fastboot, I saw that it was showing:
Even when I unlocked the bootloader.
Does that mean that if I flash the ROM the secure boot check will fail and the phone won’t boot? Does it mean that it will not even let me flash? Or should I even flash? I have formatted my phone so I could continue before I saw that. Though there wasn’t any important data in it.

Any help is really appreciated.

I wanted to jump in and mention that if you’re looking for help for this specific topic, you might want to try asking for help somewhere that focuses on Galaxy or your specific product. It’s definitely possible that another GitHub user might have run into this same issue and can help, but the GitHub Community Forum focuses primarily on topics related to GitHub itself or collaboration on project development and ideas. We want to make sure you’re getting the best support you can, but this forum may not be the right place for this particular topic.
