Hi @Zalavadiya, Harsh ,
Welcome to Q&A Forum!
From my research and testing, we cannot Side-by-side Column field on card of Board view in SharePoint list. In other words, Board view cards can only display one field per row by default.
This is because there is no syntax command to set this feature in the Board view. For more information, please see "Board view customizations" article.
Thanks,
Echo Du
