Product: HP EliteBook 650 15.6 inch G9 Notebook PC (4D171AV)

How do i install the new MS certificate for secure boot?
Latest BIOS update installed SP161510, after that started an unknown MS Update at startup, but certificates not installed. Should be in the latest KB5065431.
Thx in advance 

best regards 

Frank
