My Employer has no provision of VPF - Is there an offline process through which i can opt for Voluntary PF in my PF account?

My employer is deducting my EPF @12% rate of my basic for both the contributions as per the rules.
However i want to contribute more by opting for Voluntary Providend Fund. When i asked my employer for the same, the finance department said, "We do not have that provision of increasing your PF".
1) Can the employer deny like that for VPF?
2) Is there an offline process through which i can opt for Voluntary PF in my PF account?

VPF is possible only when the employer and employee both get agree on increased contribution,
above 15000/- ceiling VPF does not remains attractive as the EPS and EDLI are having ceiling at 15000/-

Dear all,
I want a small help about VPF.In ECR there is no option of VPF.We already registered in EPF.So is there any separate provision again we need to register in VPF ??
Please let me know the complete procedure for VPF filing.And also please share any form or registration doc.for voluntary pf.
