css – Is there a safari IOS feColorMatrix fallback?

I’ve an angled gradient svg form that breaks up into items on Safari IOS. It appears to be as a result of safari IOS does not assist feColorMatrix (and many others).
Has anybody else handled it earlier than and might suggest a fallback that might be applied?
