Both pip and sip-install are front-ends to the same back-end. pip 
supports downloading, sip-install is easier to use.

The option is actually --config-settings...

     pip -v install --config-settings --qmake=/path/to/qmake 
--config-settings --confirm-license= /path/to/PyQt5-5.15.7.tar.gz

The -v is recommended but not required.

That is distro-specific.

Either install sip in the venv or run sip-wheel instead of sip-install 
and use pip to install the resulting wheel.
