Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and re movals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint , e.g. "composer require v17development/flarum-seo:*" to figure out if any versi on is installable, or "composer require v17development/flarum-seo:2.1" if you k now which you need.
