Don\'t allow build if default choice is selected in choice parameter Jenkins

Question

I want to make it function like when ENVIRONMENT is selected as None Build button should not appear or it should not be clickable or should give error live ENVIRONMENT is required!.

@Library('shared-library@main') _

pipeline {
    agent any
    options {
        disableConcurrentBuilds()
        buildDiscarder(logRotator(numToKeepStr: '40', artifactNumToKeepStr: '20'))
    }
    parameters {
        choice(name: 'ENVIRONMENT', choices: ['None','development', 'development2', 'development3', 'development4'], description: 'Environment to be built')
        string(name: 'BRANCH', defaultValue: 'intermediate_release_1.21.0', description: 'Branch to be built')
    }
    stages {
        stage('Repo clone') {
            steps {
                git credentialsId: 'jenkins-automation-github', poll: false, url: 'git@github.com:example/example.git', branch: "${params.BRANCH}"
            }
        }
        stage('Build') {
            steps {
                script{
                    APP_NAME= 'XXX'
                    REPO_NAME= 'XX' + APP_NAME
                    ACCOUNT_ID= 'XXX'
                    ENVIRONMENT = params.BRANCH

                    build(REPO_NAME, ACCOUNT_ID)
                }
            }
        }
    }

For this you can use the Active Choices Reactive Reference Parameter. Have a look at this.
