I don't understand what makes you aggressive for the update. Odin flash is safe. However, INS firmware on a BKD device may cause several functional errors (Network issues). Samsung released the firmware in india and they are working on the updates for BKD, SLK, and NPB (new build on checkfirm). They are all in the ODM channel. Sooner or later you will receive the update. Also, this update will not make Galaxy A50 a S21 Ultra but some new features. I hope you understand.
I won't recommend you to do so bhai, This can cause serious problems in your device. So better wait for the official update which will be pushed to your device soon dw.
