DS90UB934-Q1: Can 934 support different voltage level for I2C and GPIO respectively??

Part Number: DS90UB934-Q1

Hello team

I hope you are stay health and safe.

My customer has question that if they can use different power of I2C from GPIO.

while I search this in data sheet, there is option for IO_CTL.

here are question as below.

1) is it possible to support different power between I2C voltage and GPIO voltage??

2) if yes, is there any register configuration is needed??

3) if not, is there any register configuration is needed if customer will use 3.3V I2C power??

Thanks for team's support as always~
