Storing media in a non www folder but accessing it love lace using gallery-card

I use the gallery-card love lace plug in along side the files component.

Here the files component creates a list of files and presents it to the galary-card card for use on a Lovelace dashboard.

The problem is for the content to be accessible i need to have the media in the /config/www/cctv folder. The media i am wanting to see on the galary-card card is CCTV footage so putting those video files in /config/www/ means that anyone can access them through https://ha.xxx.com/local/cctv/<filename.mp4>. This is not ideal.

Does anyone know of a way that I can keep my cctv footage in /mnt/cctv and still access it through a lovelace card?
