Of course you can not. But But what I've experienced was that I had to turn on tracking on the handcontroller to resolve. The INDI correctly indicated that the tracking is off, but it was unable to turn tracking on. This may be a bug in the INDI driver.
But I've already experienced that synscan can turn off tracking in some situations (not randomly, but I cannot figure out the logic behind the behavior), especially the synscan app on the phone prone to that annoying thing.
I have been using HEQ5-Pro and EQ6-R mounts for the past three years with Ekos and also found that using the hand controller is error prone. Ever since I switched to using an EQMod cable all my problems have gone away. I am using this one
and according to page 6 of the AZ Goto manual that cable fits on the mount as well. Perhaps it is a solution to your problems? I'll have to say that I tried using the cable with a 12" SynScan dob as well and it didn't work due to a different command set wrt equatorial mounts. But that was over two years ago and perhaps Ekos now supports that as well.

My dream is to control the mount with INDI directly without synscan, but I had no success so far. I was trying indi_skywatcherAltAz driver but had no luck. The driver can talk to the mount, but not working correctly. I've tried with my Virtuoso mount (for which is the driver designed for) and my 10" dobsonian, but neither works correctly.
One of my (many) problems is enabling debuging. On the INDI Control Panel I have a Debug option, which is Disable by default. When I click Enable it seems to toggle to enabled, but in less than a second it turns disabled again.
In the log window it says:
2020-02-09T18:06:17: [INFO] Debug is disabled.
2020-02-09T18:06:16: [INFO] Debug is enabled.
Meanwhile I've figured out that it was the Ekos that kept re-disabling debugging. I've enabled verbose logging instead of regular logging in Ekos and now debug is enabled on the INDI control panel. Most probably it would also work if I just disable "Log Output: To Client" on the INDI control panel.
That was the peace of information I was missing.
