Hi @NavinMdr

Yes it is possible to upgrade theme only !

But you will required to update theme manually , if theme providers has not given any console to directly update the theme.

So here you will required to download the latest version of the theme - then replace with existing theme in app/design directory.

then you will required to run below commands : 

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:clean
php bin/magento cache:flush

Your theme new gets installed after this !

Note : Before updating theme - make sure you take a backup of existing site along with its database so if you found any conflict-ion then you can easily recover your site !
