Q.What Should I Do For Spots On Agapanthus?
I have 2 garden beds edged by agapanthus, they were planted before I moved in so 10 yrs + and are a bit crowded now. This summer brown spots have appeared on the leaves, google says it’s likely fungal & to get rid of affected plants but that’s all of them ? is there a way to treat affected plants?

I don't think you need to get rid of them. Try spraying them with Neem oil. Here is more about their care and diseases.
