How to upgrade Qt in Jetson AGX Orin

Hello everyone,
I have a Jetson AGX Orin with jetpack 5.1.2 that includes Ubuntu 20.04 and qt version 5.12.8 pre installed.

$ qmake --version
QMake version 3.1
Using Qt version 5.12.8 in /usr/lib/aarch64-linux-gnu

I would like to update to version 6.4.7. What would be the best way to do it?
I THINK that the installation it comes with is a lite version (maybe boot to Qt?), since I can’t find the maintenance tool, for example.
Is there any way to update this version?
If I have to install version 6.4, how should I do it? Should I compile and install from source code?
Any help is welcome.

Thanks in advance

Don’t mess with the system libraries!

Compile your own. Install them into a custom directory (e.g. /opt/company/own_qt-6.7.8).
Use linker options to link your own applications to that specific version.

optional: make .deb packages for easier deployment.
