[TYPO3-mvc] Remove chash from a form view helper

[Mam Violeng]

Hi All,

Is there any way that I can remove chash uri from the form viewhelper 
like <f:form ... useChash="false">..</form>.
My current solution, I created new form view helper by extend fluid form 
viewhelper and setUseCachHash(0).

I would like to know if there is already exiting setting in fluid form.

Thanks,
Violeng Mam
