At least for Airflow 2.10 this is working for me:
In the Airflow UI, when I click on the DAG and then the "Graph" tab, I can select the task node I want to not execute for now, and mark it as "Failed" using the "Mark state as..." button at the upper right. The DAG run will stop at the node before that marked node. As soon as you want to proceed, just click the "Clear task" button while selecting the node that you marked as "Failed" before, and the DAG will proceed with that node.
