Will it do it either way, yes. Is it necessarily smart, no. APPR/VNAV (VGP) is used for DA because it won't level itself off at a selected altitude. If you select NAV/VNAV (VPATH) it will level at the first altitude reached (selector or VNAV alt). Which is, why it's better to use NAV/VNAV (VPATH) for MDA mins for continuity.
