Prevent updating from 4.3 to 4.4

My setup is Nvidia Jetson Xavier NX Developer kit with jetson-nx-developer-kit-sd-card-image with /etc/nv_tegra_release REVISION 4.3.

Im using drivers for Raspberry Pi Camera. (https://github.com/RidgeRun/NVIDIA-Jetson-IMX477-RPIV3/tree/master/patches_nx). And there is no drivers for new nv tegra revision (4.4). There are only for 4.3 . But when i try to apt-upgrade - it automatically updates to new nv tegra version and breaks my compatibilities.

How to disable those automatic updates, but still have my custom packages be updated by apt-upgrade?

There’s a file at: /etc/apt/sources.list.d/nvidia-l4t-apt-source.list. Comment the entries in that file, save and exit it. Run apt update, it should make sure that during apt-upgrade, your JetPack version is not updated/upgraded.
