Lol she does sound active. Adding a lot of substrate might help possibly - not sure how much you have now but you could easily get 20 to 25cm depth of substrate in that cage and she might turn to digging tunnels instead. Plus scatter feeding maybe. Sometimes they feel there is too much open space in a large cage, so deep substrate and a shelf or two might help rather than chew toys (or as well as chew toys). I wouldn't use "rope" though as it is bad if chewed. Sisal string or rope is supposed to be ok.
Maybe you could make a couple of platforms (if you don't have any) A piece of wood and stick some long legs on so it will sit above 25cm of substrate. Then she can dig and burrow, sit under a shelf or sit on a shelf as well with extra toys on a shelf. Sometimes a big house helps as well. If you have deep substrate though there's an issue with heavier things sinking on them if they burrow underneath, so maybe put heavier things on the shelf and just have light toys and a light house on top of the substrate. A large shoebox house might be nice as then she has somewhere to retreat to in the dark and can also chew it
