All phones can get rooted by means of ADB having the correct SU-binary at your hands: Rooting Android is done by simply adding SU-binary to Android OS.

Ye, I have read some guides but the problem is to install SU binary I have to flash no-verity-opt-encrypt and for that, I have to use TWRP but TWRP is not working the only device and Thanks

Question
Does Samsung Devices support fastboot if doesn't can I install it (I have a20s how I put that in recovery mode) ??

For A20s (A207) a root method has not yet been devised.
They are working on it here
