Welcome to the Q&A Forum

Depending on the topic, there was a update recently called the freshness update, where fresh content would rank higher, but this is only for certain topics, such as sports where the news is valuble while it was fresh but of little value once old. but for evergreen content it did not make any difference. You can conrtrol indexing though your sitemap.xml. you can tell it how often your content is updated, but bing have said if you dont tell the truth in your sitemap, your site will lose trust. My advice, for most content you do not need to update it, tell the truth in your sitemap, you dont need to get indexed often if you dont update often. If it is good content you should do well.
