Running windows on Silicon?

I'm a big fan of MacBook hardware, but mostly due to work requirements I need a lot of windows. My setup for the last 10 years was MacBook pro with bootcamp, so I would boot directly into windows and would have nothing from max os. So now i need new hardware, silent/quiet, and I need windows. Besides windows I also use reaper DAW and fusion CAD. Since bootcamp is not coming back my only hope is parallels,but it have never used it. I understand it can open windows applications in separate windows, but can I have the same behavior as in bootcamp, meaning booting and having windows environment without any mac os? So when it restart a computer I will have windows? I'm thinking of of getting the upcoming MacBook air, because of fan less design.
