Thank you very much Phil!
I tried to disable spi0 by uncomment the dtparam=spi and added instead the dtoverlay=spi1-2cs,
but still the same issue.
It seems they still think they are inputs although i switched the spi0 off and the uart3 & 4 is configured.
This is how it is ectrically done on my mainboard to the CM4.
If i dwitch of my software running as a service it shows the correct pins.
As soon as i enable it again
I definetly not using those pins.
I must check whether it has something to do with the pi4j2 library, which is doing something like PI4J.newAutoContext()
