Perhaps:

\version "2.20.0"

forceSharp =
\tweak Accidental.stencil #ly:text-interface::print
\tweak Accidental.text ##{ \markup { \sharp } #}
\etc

forceFlat =
\tweak Accidental.stencil #ly:text-interface::print
\tweak Accidental.text ##{ \markup { \flat } #}
\etc

\relative {
  \key f \major
  f' g a \forceSharp b
}

\relative {
  \key g \major
  a' g \forceFlat f e
}

This probably has to be customized if you use mensural glyphs.

Best
