GTM Virtual Server Discovery on Redudnant BIGIP

I would like to know if it is possible to enable "Virtual Server Discovery" on GTM Redundant BIGIP. I found a manual (Setting Up a Global Traffic Manager Redundant System) in "Ask F5". The manual told me that I should disable the "Virtual Server Discovery" when I create a BIGIP Redundant system in Datacenter.

 

 

Below is my current environment. I have four BIGIP Systems. Two with GTM and LTM enabled (GTM_A LTM_A1, GTMB LTM_B1) and configured as redundant system and another two with only LTM (LTM_C1 and LTM_D1) also configured as redundant system.

I would like to know if it is possible to enable Virtual Server Discovery on GTM_A and GTM_B so that they can discovery virtual servers on LTM_A1, LTM_B1, LTM_C1 and LTM_D1.
