Lovelace - How not to show seconds with input.datetime with multiple-entity-row card

[Merangle]

Hello

I’ve have defined an input.datetime with has_time:true.
If i use it with an entity card i see only hour:minute

if i use it in an multiple-entity-card i see hour:minute:second

Do you know how to show only hour:minute with an multiple-entity-card ?
Thanks
