Is the Moto E4 Plus (XT1775) supported for SIM unlocking?

Hi, I saw that SigmaKey now supports Moto E 4 models for SIM unlocking and the image that pops up when I open the program lists the model "XT177X". My model that I need unlocked is the XT1775 which is locked to Consumer Cellular, but I have been unsuccessful in unlocking it.

Does anyone have a guide to unlocking this model or can let me know if it is not supported?

Thanks
