I need to downgrade FAP-U431F from "8.6-0build-7-11ax-1" to "8.5-2build-5"

[Venix77]

Hi! Im running a MC3200 controller with the 8.5-2 build with several FAP-U321EV with the same version. I've recently needed to install 3 additional APs of version FAP-U431F that defualty run the "8.6-0build-7-11ax-1" version. According to the Fortiwlc_Support_matrix PDF FAP-U431F should be compatible with my MC3200 controller if it runs the 8.5-2 firmware. So my question is. How do i downgrade my FAP-U431F frimware to the compatible version? See pictures.
