How to change Orin spi pins output level from 1.8v to 3.3v?

I use a Nvidia Orin as a SPI master and connect to a mcu as a SPI slave. The IO level of orin is 1.8v while mcu is 3.3v, so that we have to use a level shifter. Are there any method to remove this chip and link orin and mcu directly?
I have tried to change pin register E_IO_HV to 1, than spi pin have no output. I want to make sure if orin’s spi has the ability to output 3.3v.
Thank you very much!

No, SPI is 1.8V only, you should use level shift for that.

ok, thank you for your reply!
