Dynamic CPU and Memory through helm chart

I’m currently specifying CPU and memory values through a Helm chart, but I’d like to make these values dynamic. Instead of a dropdown, is it possible to use a text box for entering values dynamically?

  startTimeout: 1200 
  profileList:
    - display_name: Data Science CPU
      description: "Select from the below available images"

              display_name: "PySpark 3.5.0 + Python 3.11"
              kubespawner_override:

        cpu_memory:
                display_name: "CPU and Memory"
                choices:

                      cpu_limit: 4
                      mem_limit: 8G

It should be possible, see the unlisted_choice option:

The unlisted_choice option is not operating without choices option and also i am not able to add multiple values.
