I feared so, but my termux rebuild showed opencl as only available hw
device for internal ffmpeg:

~/cinelerra/cinelerra-5.1 $ thirdparty/ffmpeg-5.1/ffmpeg -init_hw_device
Supported hardware device types:

after I modified my build script.

~/cinelerra/cinelerra-5.1 $ git diff blds/termux.bld
diff --git a/cinelerra-5.1/blds/termux.bld b/cinelerra-5.1/blds/termux.bld

So, for some reason your ffmpeg build as done by cingg does not pick up
those opencl variables?
