Can I Deduct Computer Cost If Only Starting Using it a Lot for Business in Year 2 of Business?

I purchased a computer in early 2021 that is for personal use and use for my business (a sole proprietorship).  My business didn't begin until November 2021, so a very small percentage of the computer's use was for business in 2021.  Can I claim any of the computer's cost as a business expense for 2021, or for future years (when I expect to use it 60% for business)? Or am I just completely out of luck because I didn't use it enough for business in the year I purchased it?
