I think what you are asking for is extra-spacing-width, but it might be easier
to use repeatTie instead of slur.
##############
\version "2.23.11"
\relative c'' {
b1
a \repeatTie
\tweak extra-spacing-width #'( -5 . 0 )
c \repeatTie
d, \repeatTie
\tweak extra-spacing-width #'( -5 . 0 )
a \repeatTie
}
