And for an automated approach:

%%%%
\version "2.22.0"

#(define NEAR -1)
#(define FAR 1)
flattenPositions =
#(define-scheme-function
   (rel-pos) (number?)
   (grob-transformer 'positions
    (lambda (grob orig)
     (let* ((dir (ly:grob-property grob 'direction))
            (ys (ordered-cons (car orig) (cdr orig)))
            (y (interval-index ys (* dir rel-pos))))
      (cons y y)))))

{
   \override Beam.positions = \flattenPositions #NEAR
   g''8 b b c'' a' b'' b'' d'
   \override Beam.positions = \flattenPositions #CENTER
   g''8 b b c'' a' b'' b'' d'
   \override Beam.positions = \flattenPositions #(* 2 FAR)
   g''8 b b c'' a' b'' b'' d'
}
%%%%
