install unknown app all disable

[nadrah]

Hello there...

Im having an issue with my samsung A51.. I tried to downloading an APK file..When i click to install it, a screen pop saying i need to uncheck the "allow install unknow apps"

The button is disable/greyed out and there is no way i can move it to enable.

Would really appreciate if someone could help because at the moment there is no chance of me downloading any app that isn't available on play store...
