Change Conditional Tag

I’m using the rebelpixel plugin for recent links (https://rebelpixel.com/). The archive page for those links is considered an is_year conditional tag. I want to change that to something else, maybe even create a new condition because I want different sidebar content than when viewing the regular post yearly archive. Currently, whatever I set to display for is_year will display on my post yearly archive and on the recent link archives.

How can I have more control over the conditional tag assigned to a page? How can I even check to see what conditional tag has already been assigned to a specific page? Thanks.
