Does Amplify's SSR feature have execution time limits like Lambda function?

Well, I deployed my Next.js 14 app with server actions to Amplify with SSR feature. My app contains heavy tasks that render pages and produce PDF reports on the server side in real-time, and these logics are executed as Server Actions of Next.js 14. While those heavy tasks were used as lambda functions, without changing the default execution time limitation, sometimes exceeds the time limitation. My concern is whether Amplify SSR feature has the same execution time limitation. If there is the execution time limitation, is it possible to change the time of timeout?
