define jenkins agent jnlp container memory specs via pipeline

Question

Team,

I need to create a custom jnlp jenkins-agent container with custom memory spec. is there a way i can define it in pipeline? I already created template for it but don't know how to tell jenkins to use. if i change the default spec it will effect all jobs, I just want my pipeline to use that container.

requirement is to override the DEFAULT jenkins JNLP pod spec

11:05:29        limits:
11:05:29          memory: "8Gi"
11:05:29          cpu: "8"

11:05:29      name: "jnlp"
11:05:29      resources:
11:05:29        requests:

so if you observe above.. the bottom lines are jnlp. these are not defined in pipeline..this container is default from jenkins.

11:05:29      name: "jnlp"
11:05:29      resources:
11:05:29        requests:
11:05:29          memory: "256Mi"
11:05:29          cpu: "100m"

my pipeline is below

pipeline {
  agent {
    label 'ui'
  }
  parameters {
    string(
.
.
.
    )
  }
