Ublox M8 on C027 i2c address

It appears the i2c address for the MaxM8 on the C027 is set to 0x66<<1. Is it possible to change the i2c address programatically or is the i2c address fixed on the M8 receiver? I haven't found any good information in the datasheets for the M8 on this topic.

Check section 10.5 DDC Port of this document: https://www.u-blox.com/sites/default/files/products/documents/u-blox8-M8_ReceiverDescrProtSpec_(UBX-13003221)_Public.pdf

Message CFG-PRT will allow you to do this.

Thanks Michael, that helps a lot!
