Exhaust all paths between two or more vertices

Is there some way to go on a path finding mission with repeat().until() type construct that avoids the early stop observed while the until condition is first met? That is, without skipping .until() for .times().

Find all paths between two vertices

Not sure this makes any sense, but here goes. Could someone please provide a solution to how one would avoid dead-end paths to be traversed, i.e., how can one avoid multistep traversals following .bothE().otherV() to return to self? Here's my non-working query

g.V().has('lbl', 'DexpiElement').has('tagname', 'tagA') \
    .emit() \
    .repeat( \
        bothE().has('lbl', within('HAS_CHILD', 'HAS_CONNECTION', 'HAS_NODE', 'CONNECTED_TO', 'MAIN_CONNECTED_FROM', 'MAIN_CONNECTED_TO', 'HAS_GRAPHICS')).dedup().otherV().simplePath() \
    ) \
    .until(has('lbl', 'DexpiElement').has('tagname', 'tagB')) \
    .simplePath() \
    .has('lbl', 'DexpiElementGraphic') \
    .valueMap()
