Realize it or not, you are already doing it. Integrated graphics chips don't really have their own pool of memory to use, so instead they use the system memory. A portion of this is segmented for use just by the iGPU.
For example, if you have 8 GB of system memory, but you check with a monitor and it says you only have something like 7.5 GB for example, it is because the 0.5 GB is allocated for the integrated graphics.
Is this a laptop or desktop system you are using? If it is a laptop, unfortunately you may not be able to change the amount of RAM dedicated to it. Although, in my laptop when I increased the RAM I had, it likewise allocated more to the integrated graphics. I don't have any options in my laptop though to increase this amount in BIOS. If you have a desktop, you can change this amount, but you would be better off buying a dedicated GPU, as even a $50 GPU would give considerably better performance.
One more thing, although the maximum amount of memory that can be allocated to the Intel HD 4000 graphics is 2 GB, most systems I have encountered do not allow for more than 1 GB to be shared. This is probably because the Intel HD 4000 graphics really can't take advantage of 2 GB of memory, it simply isn't powerful enough to play games at that resolution or with those kinds of settings. 1 GB ends up being plenty.
