[kucingkembar]

sorry for my bad english,

i have this folders :
-xxx park jan 2020
-yyy zoo jul 2021

I like to auto remove if duplicate picture(s) located in "unknown" folder,
but if both in "unknown" folder, delete only one of them,

You can sort by the "In folder" column in the duplicate image table, and then you'll find that your Unknown directory is always the first or the last picture in all pairs. Then select all the rows, delete first/second pictures in selected results.
If your Unknown directory is not always the first or last one, change the directory name so that it is always first or last.
