I have a YUV 444 10bit video, but when I used Avidemux's filters to burn in subtitles, the output was YUV 420 8bit. How do I get it to match the input video codec?

The internal interchange format in Avidemux is YV12 (8-bit YUV 4:2:0 with U and V planes swapped). In other words, there is no way to preserve 10-bit YUV444 in Avidemux, except for the copy mode.

So it's impossible to change the video codec for the output when using filters?

The pixel format will have been YV12, so whatever the encoder does with it later, the information lost is not recoverable.

So yes, there's no way to get anything other than YUV420 8bit for my videos when using burning in subtitles?
