We want to block the pagination URLs from Google & other search engines, is this possible without blocking in robots.txt?
You can tell Google which pages are pagination here:
Enter in the parameter of your pagination pages and you can select the dropdown that says that these pages paginate.
If you don't currently have a parameter that you can use for your paginated pages you can add them by 301 redirecting your current pagination to the parameter URL.
You can also add rel=canonical to your pagination pages though it's not as good of a solution as the crawl url parameters feature in search console.

Or perhaps, you can block Google bots from accessing these pages at your robots.txt file:
Disallow: /*?page= Disallow: /*&page=
