I2C communication in UEFI shell

Hi,
I'm trying to develop I2C application in UEFI shell.
But the simple I2C device scan efi program(build by edk2) fails to get the i2c master under extreme i14 UEFI shell. The same program could get I2C master under Intel LNL RVP board. I think its because of extrem i14 lack the Intel serialIO driver under UEFI. Could you look into this issue?

The protocol is query by gEfiI2cMasterProtocolGuid which is:
GLOBAL_REMOVE_IF_UNREFERENCED EFI_GUID gEfiI2cMasterProtocolGuid = { 0xcd72881f, 0x45b5, 0x4feb, { 0x98, 0xc8, 0x31, 0x3d, 0xa8, 0x11, 0x74, 0x62 }};

Do you have any progress？

No, I tried loading EDK i2c driver manually. It does not work. I can only working on LNL board now.
