How to control PX4 in Stabilized mode when RC enabled

Hi all!
I’m trying to control Pixhavk in Stabilized mode via MANUAL_CONTROL message, which I send to PX4 at a frequency of 10 Hz. But, when RC is connected, PX4 goes into the mode, which is set on the RC and stops responding to the MANUAL_CONTROL message.
Is it possible to control via mavlink in Stabilized mode while the RC is on?

I have the same problem. Have you solved it?
Can you give me some advice?
Thank you!

Hi! I several years do not develop UAVs and I haven’t solved the problem for as long as I can remember.

i guess it’s not a easy question.
