I have template for windows servers and i create 3 DCI for Free, Used, Total HDD values, and add DCI for C: D: E: drives

Not all my servers have so many HDD, so now i need to disable some of them or just remove from perfomance tab if there no such disk exists on system.

Is there a way to do so?

I'd suggest doing away with statically configured DCIs for disk space and replacing them with Instance Discovery ones, which will pick up any volume in your system for monitoring purposes without you having to hardcode any of them. There is documentation on that topic and there are quite a few examples on the forum on that topic, so a quick search should yield some results.
