I could do it in 1 minute:
Dear Border Patrol, please do your jobs as expected under the law, and if any manager tells you to do anything that prevents you from controlling our border please arrest them for sedition and bring them to me. Thank you. Your Boss, the President of the United States.
Dear ICE, please do your jobs as expected enforcing the laws, arrest and deport illegal aliens, and arrest and charge those conspiring to give them jobs, housing, or transport them, and if any manager tells you to do anything that prevents you from your duties please arrest them for sedition and bring them to me. Thank you. Your Boss, the President of the United States.
Problem solved.
