Showing blocks as cards

Hi all - possibly a stupid question, but I can’t work out how to show blocks as cards, or if it’s even possible. Essentially the code below just lists each entry as a seperate block in the default list layout, but I want to be able to show each one as a card (as in layout:cards). Is this possible without using the default gallery block? Very crude example of what it is now and how i want it to look with cards below. Thanks!

fields:
  blocks:
type: blocks
fieldsets:
  teamMember:
    name: Team member
    label: "{{ teamName }}"
    icon: user
    fields:
      teamName:
        label: Team member name
        type: text
      teamRole:
        label: Team member role
        type: text
      teamPhoto:
        type: files
        layout: cards

you can change how your block is displayed with a custom block preview. But to have them in rows, you probably need as nested structure.
