Adding prefix/Suffix to attributes using lovelace-multiple-entity-row

Do not try using options which are not specified in Docs as available)))

You may add an additional “column” between & specify an icon looking like a separator:


Also, add “tap_action: none” for this icon…
More compact:

type: entities
entities:
  - type: custom:multiple-entity-row
    entity: sun.sun
    show_state: false
    entities:
      - attribute: next_rising
        format: time
        styles:
          margin-right: 0
      - icon: mdi:slash-forward
        styles:
          margin-right: 0
          width: 24px
        tap_action: none
      - attribute: next_rising
        format: relative
