This is field bindweed (Convolvulus arvensis). Most people consider it a weed and it's on the Class C noxious weed list. It doesn't require control, but most do tend to try to manage it, because it can be invasive and take over spaces, including the lawn and your landscape beds. However, a "weed" to one person might be a desirable plant to another.
Mechanical removal is tedious and would require pulling and pulling and pulling and pulling on a regular, consistent basis. If you want to use chemistry, there are effective options to consider in the lawn - one of the most effective chemicals is quinclorac. In landscape beds, your options are to pull it, use mulch, or use a non-selective herbicide.
Bindweed is considered to be "noxious" for many reasons. Since it's a list C weed, it is recommended (but not enforced) to control it: https://ag.colorado.gov/conservation/noxious-weeds/noxious-weed-species-id/field-bindweed
And here's an article from neighboring state, Nevada, that may also provide some context: https://extension.unr.edu/publication.aspx?PubID=3762
Once established, the plant can be very difficult to control - and it has the ability to take over desirable plants.
