How can I use 5850-5895 for PTP in Canada?

I’m under the impression that this “upper 5GHz” band is allowed to be utilized within Canada.

D4 - “ISED will allow all licence-exempt RLAN devices to have immediate access to the 5850-5895 MHz band for indoor and outdoor operations once appropriate technical standards are in place.”

Back in 2020 when this band was made available for use, I believe there was firmware available from Cambium Support that would allow this to band, but I’m unsure how to obtain it now.

Can anyone point me in the right direction?
