I just tested a similar commandline on the same driver:

./ffmpeg_g.exe -v verbose -init_hw_device cuda=cuda -filter_hw_device cuda -hwaccel_output_format cuda -hwaccel cuda -i recode.mkv -i test.png -filter_complex "[1:v]format=nv12,hwupload[p],[0:v][p]overlay_cuda=x=100:y=100" -an -c:v h264_nvenc -y out.mp4

And that works perfectly fine on a RTX2070S. Make sure your driver installation is not somehow damaged.
