By default they don't exist, but they should be fairly simple to add. You just have to add your own "tag" class in src/mem/cache/tags. So, I'd just copy the existing LRU files, rename them something different, then edit them to implement them to be what you what (doing search/replace within the new files to reflect the name change). Then edit the Tags.py file to reflect the new tag class.
After that, you should just be able to replace the "LRU" cache policy with yours when the system is constructed.
