Facing issue related to DSC

So I've been using older and newer version of adobe reader, last time I was using adobe reader XI and it had the option available to place signature using certificate (DSC) but I was facing some error and chose to update it to the latest adobe reader DC version and when I clicked on the sign icon there's only option to place initial and draw signature, DSC feature is nowhere to be seen, I'm in the urgent need of it, can anyone tell me how to enable DSC in latest adobe reader or at least provide a suitable older version which supports DSC.(window 10 64bit)

I'd be grateful if anyone could help me, it's urgent

Thanks
