As others already said, the roundness (i.e. the blot-diameter) is hard-coded.
Though, you could look into the default-stencil and return a modified
one instead.
Beware this depends on the current representation of the stencil,
which may be changed in future versions.
NB Not tested beyond the given example!

\version "2.26.0"

#(define zero-blot-ledger-stencil
  (lambda (grob)
    (let* ((stil (ly:ledger-line-spanner::print grob))
           (stencil-expr (ly:stencil-expr stil)))
      (ly:make-stencil
        (list-map
          (lambda (l)
            (if (and (pair? l) (eq? (car l) 'round-filled-box))
                (append (drop-right l 1) '(0))
                l))
          stencil-expr)
        (ly:stencil-extent stil X)
        (ly:stencil-extent stil Y)))))

\layout {
  \context {
  \Staff
  \override LedgerLineSpanner.stencil = #zero-blot-ledger-stencil
  %% For testing purpose:
  \override LedgerLineSpanner.color = #red
  \override StaffSymbol.line-count = 1
  \override StaffSymbol.thickness = 5
  }
}

{ b''4 }
