Thumbs up Android block firmware FLASHING by ODIN

Is there anyway or application or method to put on my actual firmware that i prevent anyone from touching it?

I want to prevent or block FLASHING by ODIN in download mode, mainly!!

Example: I have a security software installed, i want to prevent any thief from flashing a new firmware and removing my security app from it.
NOTE: I know how to keep it working after wipes, and removing OTA updates from device, but i want to prevent a FLASHING by ODIN tool by PC.

Any expert here knows a method to remove the DOWNLOAD MODE???
