No man. That's no the function of the developers option. What you just described is
second space and it is available in some Redmi, Samsung, Oppo and Poco android phones.
"
Second Space is a feature in MIUI (Xiaomi's Android-based operating system), creates a separate, independent environment on your phone, essentially giving you two separate "phones" in one. It allows you to have different apps, files, settings, and even a different unlock method, all within the same device."

I guess I’ve been missing something all these while and for a country like ours where the security agencies(police) is a no friend to a crypto holder, then the second space feature should be a way out for the common man.
I am curious to know if these feature also works for IOS devices and other android devices that were not mentioned in your post?
