Steam VR starts when i start MSFS2020

Since the new update when i launch MS2020 (Windows App) the FS is loading, when the Startmenu appears suddenly Steam VR starts automaticly even the VR Mode of MSFS isn’t acive. I have to quit Steam VR everytime.

Shouldn’t Steam VR just start when i activate the VR Mode ingame?! How to fix this?!

Thank you in Advance.
