Disable the touch when the joysticks mode is enabled in the mobile version

I’m sending a project on an external portal for pixel streaming.
But when I go to browse in the mobile version with joysticks enabled it also gives me the touch and so it is impossible to navigate.
How can you disable touch functionality while keeping the joysticks mode active on the mobile version?
I would like to browse only with the joysticks as I did in this video:

thank you so much
