You mean dynamically change the flow card definition? I don’t think that’s possible. The predefined JSON definition will always count.

Yes, I’d like to dynamically change the min/max values ​​of numeric arguments in a flow card. For Capability, you can use Device.setCapabilityOptions to change the min and max values ​​for a capability. I’m wondering if this is also possible for flow card arguments.

I haven’t seen a possibility to do that. It’ just predefined in JSON definition of the flow card.
