Hide the icon in card_graph (Lovelace UI Minimalist)

Hi, I recently started using Lovelace UI Minimalist.
I’m trying to hide the icon in the card_graph to save space and move the text all the way to the left.

Is it possible to achieve this using an attribute, or do I need to create a custom card?

- type: "custom:button-card"
  template: card_graph
  entity: sensor.temperatura_rustico
  variables:
    ulm_card_graph_color: "#4682B4"
    ulm_card_graph_name: RUSTICO
    ulm_card_graph_entity: sensor.temperatura_rustico
    ulm_card_graph_type: fill
    ulm_card_graph_hours: 24
    ulm_card_graph_group_by: interval
    ulm_card_graph_line_width: 5

Thanks a lot!
Simone
