yes, currently working on that,
opencv did not change anything though

interestingly running the following command eliminates the warnings, but reintroduces the segmentation error
echo "/usr/lib/aarch64-linux-gnu/tegra-egl" > /etc/ld.so.conf.d/nvidia-tegra.conf

currently still working on it, but no real progress. i started using the NVIDIA forums for anyone interested.

I have been messing around with some other bugs, but all systems are working fine now.
basically, the LibEGL warnings can be completely ignored and do not seem to have an effect on the gstreamer.
nvidia-l4t-gstreamer version also does not seem to be very important
thanks for the help

my Dockerfile in case it helps someone
