You could do \override TieColumn.positioning-done = ##t, but be aware,
using it means you are now responsible yourself for the Tie's
directions.
You tell LilyPond "Don't bother placing the Ties, I'll do"

\new Score {
  \new Staff {
    <<
      { \time 4/4 \partial 4 s4 | s4*2 }
      \new Voice = "zeroA03" \relative c' {
        \set tieWaitForNote = ##t
        <b b'>4 ~
        <b_~ b'^~>1
        \once \override TieColumn.positioning-done = ##t
        <b e f a b d>1
      }
      \context Voice = "zeroA03" \relative c' {
        s4
        s2.
        \hideNotes
        % if I remove *either* the a or the d from this chord,
        % I get up/down ties from <b b'> above
        \voiceTwo \tieNeutral <e_~ f_~ a^~ d^~ >4
        \unHideNotes
      }
      % This displays the e-f-a-d notes
      % that are the source of the 4 extra ties.
      % Doesn't matter to <b b'> tie behavior
      %\new Voice = "zeroB03" \relative c' {
      %  s4
      %  \voiceTwo \tieNeutral r4 <f a>2 ~ <e f a d>4 %~
      %}
    >>
  }
}
