[Help]: I can not set a more accurate selection than 99%.

Environment

( - OS: [e.g. Windows / Linux / MacOS ])
Docker via Portainer on a Synology NAS

Question

(A clear and concise detailed question.)

I have a lot of pictures where groups of people laugh similarly. VDF shows me these images with a similarity of about 99.5%, even though people smile at the camera at one photo and smile at each other on the other one.
I don't want VDF to recognize these images as duplicates, so i need to change similarly (or at least the filter) to more accurate then 99%

Accordingly, I would like to be able to fine-tune the search criteria or the filter for descendant positions. Instead of a maximum of 99%, I would like to set 99.6%.
However, this is not possible in the search criteria or in the filters.
How can you ensure that only photos that have 99.6% or more similarity are selected?!?

Snapshots

(Optionally, include snapshots to help clarify the question.)
Just try to change some percentage to 99,6%

TANK YOU !!
