VNAV is driven by the machine, being out of temperature envelope legally precludes you from using it. Therefore the VNAV/LNAV minima are N/A too.
One would fly plain LNAV approach i.a.w. the DIST/ALT table, having applied the temp correction to the declared values. Down to plain LNAV minima that need to be corrected upwards too! See Matey above.
