Not suspension, but this might work. They say out of stock, you would have to find out if or when it will be in stock.

You would have to verify that your bike as a rake (or offset) and a axle to crown length similar to this.
I think trying to install a disc brake and rim brake on the same wheel is not a great idea.
If you get a different fork, you probably will need to have a bike shop install your fork crown headset race. If you bought that fork, perhaps ask them if they could install the race you need on it before they ship it to you.
