Inquiry about Modifying Herelink Drone Console without User Rights

Hello,

I am in the process of flashing my drone’s console to install an application from the computer without using command lines, or to change by default the font or the design of the Herelink settings, or even to change the boot animation of our console.

I would like to know if it’s possible to do this without necessarily having user rights.

Any help would be appreciated

Thanks
