Without infos to your system no one can help you.
So there is only one answer: Disconnect the VGA monitor. Ok, a second: Set the bios to UEFI mode, meaning disable CSM. |

it's a B450M Pro4-F
I disconnected the VGA. Of course BIOS is booted in the remaining DVI monitor... Connected the VGA again, BIOS is booting in the VGA! Is it even possible to change this? |

Which GPU are you using?
Or do you have an APU using the onboard connectors? |

Look in the bios if you can find an entry for selecting the default display output.
Or as i already posted: Set the bios to UEFI mode, meaning disable CSM. |

I do a boot in UEFI Mode!
But there's no option to change the primary video device?! |

OK, in the meantime I got it how to enable / disable CSM!
But CSM is disabled. I use UEFI! But Bios is booting always with VGA! There's no setting to change the primary display port!? |
