Heatmap - to remove axis information

As @timanix proposed, you could just edit with image editing software (e.g., adobe illustrator) for a quick fix.

I may have a more "out of the box" solution for you though: it sounds like Sample and #SampleID are totally redundant and you are using --m-sample-metadata-column Sample to relabel the samples with the label that you want to display (e.g., in publication). An alternative is to use qiime feature-table group to relabel the sample IDs with any label that you want for publication. Do this:

  1. Relabel sample IDs with group following the steps described in this post. That will create a new feature table where the sample IDs are the Sample names (or any other metadata information that you want to use to relabel sample IDs)
  2. Input the new table to heatmap and there should be no need to input metadata to label with additional metadata, so your command would look like this:
qiime feature-table heatmap \
    --i-table RELABELED-TABLE.qza \
    --p-metric braycurtis \
    --p-method average \
    --p-cluster both \
    --p-color-scheme rocket \
    --o-visualization Table_Top25_VA.qzv

Good luck!
