Can a 2-column grid of info be acceptable if it mitigates an awkwardly large amount of white space?

I'm in the middle of a psuedo-overhaul of my company's platform, with an emphasis on "object-level" pages (ie the page for an individual task, or individual appointment).

A problem I'm running into is that the info for many of these pages is laid out in a two-column format (see pic), which I know any competent ux designer will tell you is bad for scanning. But while combining both columns into one single left-aligned column might improve scannability, it would also leave just a gaping void of whitespace on the right portion of the page. I can't really articulate any ux code this violates beyond just looking ridiculous and stark, but it still seems like an issue worth surfacing.

Any thoughts on this? I want to follow best practices but I also would like to preserve a sense of visual balance and appeal.

Thanks!
