How to disable 10g phy in Macchiatobin Double Shot?

1

I wan to to disable the two 10g phys in Macchiatobin Double Shot because I use SFP ports with DAC cable. The two 10g phys are very hot even though we don’t use them. I guess we can save some power consumption. Tried setting “# CONFIG_MARVELL_10G_PHY is not set” in kernel config and disabling them it DTS as below. Even though the RJ45 ports of 10G don’t work but they are still hot. I also measured the power, it doesn’t change either. Any idea?

May I know if you have any update on this issue? Can you compile the FW successfully?
