How to delete an Azure Pipeline cache without changing cache key

I have a task that creates a cache

- task: Cache@2
  inputs:
    key: 'sonarCache'
    path: $(SONAR_CACHE)
    cacheHitVar: CACHE_RESTORED
  displayName: Cache Sonar packages

However, the cache got corrupted. So how do I run this pipeline while telling it to ignore any existing cache ?

For some reason, I cannot change the cache key sonarCache
