Change of designation in CV

In my previous company my designation was system engineer in Infosys, but I want to switch my career to Devops engineer role so can I put Devops engineer as designation in my CV to attract recruiters.... because if I will mention my designation as system engineer in CV then no HR will shortlist my profile? So if I put Devops engineer as a past designation in my CV, Will it impact background verification?

For your information let me clear you: Whenever a fresher joins infosys, every fresher gets the designation "system engineer" whether he will be a software developer or tester or cloud engineer.
