@code{--with-input=mesa=nvda} or grafting with @code{--with-graft=mesa=nvda}.
For a programmatical way, the procedure @code{replace-mesa} can be used.

Additionally, if the NVIDIA card is not used for displaying, environment
variables @code{__GLX_VENDOR_LIBRARY_NAME=nvidia} and
@code{__NV_PRIME_RENDER_OFFLOAD=1} may be set.")
