Signing method for AAX in circleCI

Hi all,
For one of my company project we are generating different audio plugins in circleCI. One of them, AAX (Avid’s Protools format) needs a special signature method.

For this signing we need to have a Signing SDK installed on the signing computer and, we need a physical iLok key plugged into that computer.
Has anyone solved this problem and sign generated AAX files with Avid tools in circleCI?
Many Thanks!
