Can't change log level of the launch file

Bug report

We have a launch file that runs some nodes and executes a process.

We include RegisterEventHandler, and OnProcessExit that emits even Shutdown.

For some reason, it prints all the debug messages from the processing event.

When trying to change the default log level with rclpy.logging.set_logger_level('launch',20). it doesn't help and it print alot of DEBUG messages.

Everything is working and the simulation running, just prints a lot of DEBUG messages.

Required Info:

Operating System: Ubuntu 22.04
Installation type: binaries
DDS implementation: Default
Client library (if applicable): rclpy

Steps to reproduce issue

Some part of the launch file:

...
time.sleep(1.0)

rclpy.logging.set_logger_level('launch', 20)

def generate_launch_description():

    proc_px4 = ExecuteProcess(
        cmd=['bash', '-c', f'cd /workspaces/drone/PX4-Autopilot && {mode} make px4_sitl gazebo-classic_iris__windy'],
        cwd='/tmp/px4',
        output='screen',
        emulate_tty=True
    )

    node_offboard = Node(
        package='px4_offboard',
        namespace='offboard_control',
        executable='offboard_control',
        output='screen',
        name='offboard_control',
        parameters=[offboard_parameters],
        emulate_tty=True
    )

    node_dds_agent = Node(
        package='micro_ros_agent',
        namespace='px4_offboard',
        executable='micro_ros_agent',
        name='micro_ros',
        output='screen',
        emulate_tty=True,
        arguments=['udp4', '--port', '8888']
    )

    recorder = ExecuteProcess(
        cmd=['ros2', 'bag', 'record', '-a', '-s', 'mcap','-o', f'db/{time.strftime("%Y-%m-%d_%H:%M:%S", time.gmtime())}'],
    )

    sys_shut_down = RegisterEventHandler(OnProcessExit(
        target_action=node_offboard,
        on_exit=[
                    LogInfo(msg=(f'{bcolors.OKGREEN}The Scenario has ended!{bcolors.ENDC}')),
                    EmitEvent(event=Shutdown(
                        reason='Finished'))
                ]       
    ))

    bridge_dir = get_package_share_directory('rosbridge_server')
    node_rosbridge =  IncludeLaunchDescription(launch_description_sources.FrontendLaunchDescriptionSource(bridge_dir + '/launch/rosbridge_websocket_launch.xml'))

    ld = LaunchDescription([proc_px4, node_offboard, node_dds_agent, node_rosbridge,recorder, sys_shut_down])
    return ld

Expected behavior

printing only INFO logs.

Actual behavior

log-level stays at DEBUG.
