Unless something has changed, which apparently isn't the case here, you have to build QMQTT yourself from source, as it's not available in Online Installer for open source users.

+1.

It seems that "qtmqtt" is not a pre-built module (like "qtcharts" and "qtquick3d"). The result of Google search "site:download.qt.io qtmqtt" only gave me the url points to its source code, for example https://download.qt.io/archive/qt/5.15/5.15.3/submodules/qtmqtt-everywhere-opensource-src-5.15.3.zip.mirrorlist . However, aqtinstall, the backend of this action, does NOT support installing modules' source code or building modules from source code. Hence, you may need to download the source code and build it yourself.
