Yes. I seldom pry apart the pallets I work with. I mainly use the circular saw method for breaking down the pallets. This leaves me with plank pieces about 18-inches-long, which I then cut down to about 16-inches-long for the raised beds I like to make.
Circular saw method...
That's my favorite method. I usually save all the 2X4's as well. I just pry of the bits and pieces of wood remaining on the 2X4's and use a good crow bar to pull the nails out.
Most of my pallet wood projects are fine with the shorter 18-inch-long plank pieces. This is simply the fastest, and easiest method for me.
Modified circular saw method: You cut off both ends of the plank on the pallet 2X4's and then wiggle loose the nails in the plank in the middle 2X4 stretcher. Then it is pretty easy to pull off the whole plank piece yielding a plank about 38 inches long.
If you really need to save the full length of the pallet planks, then my next method is using a reciprocating saw to cut off the nails between the planks and the 2X4's. This will give you full length planks, which is very nice, but you have half the nail in each of the planks and the 2X4's.

I have a DIY pallet buster pry bar, but this is my least favorite way to dismantle pallets. In my experience, the pallet buster breaks more planks than any other method. However, every once in a while I get that perfect pallet for the pallet buster and then it is the perfect tool for the job. That happens to me maybe only 1-2 times in every 10 pallets I have.

Those are the main methods I use, but if you check out YouTube you might find variations on those themes. There are plenty of methods using hammers and blocks, but I think you wanted to avoid that.
Oh yeah. I can understand that as well. If time is money, then buying lumber at the store will save you lots of time. I would not pay someone time and effort to dismantle pallets and then build a project. That would not make $$$ sense.
But I enjoy repurposing pallets that I get for free. It takes me about 10-15 minutes per pallet to take them apart, and maybe that much again to remove all the nails. That's just a guess as each pallet will be different in my experience. I don't mind spending that time prepping the wood as it is just a nice hobby for me.
Then I build something like the pallet wood raised beds I like so much, grow food in them, and think about how I saved something from the landfill and used it to provide fresh food for me and Dear Wife and almost year-round frozen veggies.
Or, the many pallet wood flower planters I have built for Dear Wife which gives her so much joy. All from a free resource to me if I am willing to put some effort into the projects.
I hope some of the methods I have shown you might be useful to you. Even if you don't use pallets, maybe you can find some nice projects here on this thread and make them out of standard store-bought wood. Many of my pallet wood projects were just wood projects that I modified to work with my pallet wood. It's all good to me.
