Most people say it's not possible however, it may be possible but, it is probably not going to be easy, may not be legal, could slow down your computer and may even cause programs or the computer itself to crash. If you still want to try then here are some arduous avenues that you could take to accomplish your goal.
32-bit vs. 64-bit
The difference between 32-bit and 64-bit is that 64-bit processors can handle more data at once than a 32-bit processor. However, do note that compatibility settings may be necessary.
Possibility 1 - Recompile the driver
In theory, if you can dissemble the driver to see how it works and then re-write the driver to be functional in a 64-bit environment. However, this solution may not be legal or easy to do. This would also be harder the more complex the driver is.
Possibility 2 - Emulation
I am no expert on the internal workings of 32-bit and 64-bit drivers however, If you can emulate an entire 32-bit computer on a 64-bit computer then it should be possible.
In theory, you would need to either find or build a wrapper for the 32-bit driver. This driver would be a 64-bit driver and would act as a miniature emulator for the 32-bit driver to exist in.
However, the bigger question in this case is how fast does the driver needs to operate. The reason why this is important is because if you did manage to convert the data, it may take longer for the driver to operate and if a driver requires a certain amount of speed to operate, it could cause programs and possibly your computer to crash if your computer isn't designed to deal with slow drivers.
The plus side to this method is that you would be able to avoid legal issues that may come from decompiling the driver.
Installing Unsigned Drivers:
In order to install your driver unsigned, you will have to enter into a special mode to Disable driver signature enforcement or through a different method. Here is a link to a tutorial on how to do that:
Please be cautious when installing unsigned drivers
At the end of the day, it all comes down to how much time are you willing to spend to make a driver to function and if it is worth the risk. And so far, I have been unable to find any such drivers online.
You can force Windows to use the 32-bit driveris not possible.
