Downgrading Linux to another build


I am trying to use the ArduCam IMX519 with the Jetson Orin Nano developer kit, which it says it is compatible. I flashed Jetpack 5.1.2, Tegra 35.4.1, and 5.10.120 for the linux kernel onto the orin, but the cameras won’t work and it says it cannot find the proper build for the camera drivers. The only difference I see is my tegra build is 35.4.1-xxxxxxxxxxxxxx4926 (I forget the other numbers) - is there a way to downgrade the kernel to these other builds supported by arducam without reflashing? I have searched online but cannot find anything.
