Check if SSC is on or off

I followed the threads [1][2] on disabling the Spread Spectrum Clocking (SSC) for PCIe by patching the .dtb files as close as possible and I now re-flashed one of our Orin Developer Kits using the SDK manager.
I did this on request of a colleague, so I’m not into all the details where this was an issue.
However, is there a simple way to check whether SSC is enabled or disabled for a given clock (e.g. TEGRA234_CLK_PLLE, TEGRA234_CLK_PLLNVHS, TEGRA234_CLK_PLLGBE) during runtime, preferrably via a console command?

Thanks!

Please refer to the TRM for the detail info of these 3 registers.

CLK_RST_CONTROLLER_PLLE_SS_CNTL
CLK_RST_CONTROLLER_PLLNVHS_SS_CNTL_0
CLK_RST_CONTROLLER_PLLGBE_SS_CNTL_0
