I'm sorry, I do not see this possibility.
The h264_extradata_to_annexb() into h264_mp4toannexb_bsf replaces
extradata unconditionally.

This function calls by h264_mp4toannexb_filter() under simple
condition:
    if (!ctx->extradata_parsed) {
        ret = h264_extradata_to_annexb(ctx, avctx, FF_INPUT_BUFFER_PADDING_SIZE);
        <...>
        ctx->extradata_parsed = 1;
    }

Looks like no any parameters to avoid extradata substitution by h264_mp4toannexb_bsf.
