Hello.
Don’t know about Evernote.
Hashes are allowed in YAML as comment indicators. In the image below, you can see that #hash in the YAML is not recognized as a tag (because it is a comment), so it is not read in queries (see the example q1 hash). The #yesahash tag in the body can be queried.

#yesahash
# q1 nohash
```dataview
Table
FROM #nohash
Where file.name = this.file.name
```
# q1 hash
```dataview
Table
FROM #hash
Where file.name = this.file.name
```
# q1 yesahash
```dataview
Table
FROM #yesahash
Where file.name = this.file.name
```
