  The refined de Sitter (dS) conjecture provides two consistency conditions for
an effective theory potential of a quantum gravity theory. Any inflationary
model can be checked by these conditions and minimal gauge inflation is not an
exception. We develop a generic method to analyze a monotonically growing
potential with an inflection point on the way to the plateau near the top such
as the potential in minimal gauge inflation model and the Higgs inflation.
Taking the latest observational data into account, we find the fully consistent
parameter space where the model resides in the Landscape rather than in the
Swampland.
