Good Morning
I'm doing the same thing as you but in Azure Environment.
The Simple Answer for your question is NO.
Today only in latest Version "15.X."Something"" Can support TWO Interfaces, One of them is Management and Another is One-Arm traffic.
Being Honest I couldn't properly validate this.
I received this answer from Imperva's Dev Team
We tried to manually create more interfaces but the Gateways simply ignores them and forward the traffic all under Interface Eth0.
Also in order to use that you cannot deploy those gateways Under Marketplace path. You will need to use a Terraform Script im letting the link below:

PS: They are updating their documentation regarding this. I believe this will be ready in couple weeks.
Best Regards and Good luck.
