Nvdc:failed to open"/dev/tegra_dc_ctrl"

After I extended the system to SSD using rootONVMe, I set the system to 5W mode. After powering on the module, the error in the figure below will occasionally occur after the system is started. If I change it to 10W and EMMC, there will be no such problem, and this problem is still an occasional one, I hope you can help, thank you!!

Note: The nano module I use is a self-developed carrier. The system uses Jetpack4.6[REv2], l4T is 32.6.1 and SSD is 128 GB.

Hi 2381783554,
Nano + SSD is not coveried by our designed guide, not sure more suggestions, could you find some hints from dmesg?
