Using Time Machine to backup a Mac with Photos Library on external SSD frequently re-backs up everything

I've placed my Photos Library on an externally mounted SSD. When I use Time Machine to backup the computer Time Machine will backup the entire Photos Library instead of just what's been added. Is there any solution to avoid this behavior?

Mac Studio, macOS 15.7
