How can I do this using only three lines instead of same three lines in 3 if statements?

(Please, don't paste code as link to images: we can't search it, we can't copy-paste it, etc).
I guess you could patchValue() using computed property values (and hope that you never make a typo, because now TypeScript compiler won't catch them), but may I suggest rethinking the form and making custodian, requester and technical separate form groups, each with its phone, name and department properties?

You could do something like I did in the updateValues method: https://stackblitz.com/edit/angular-ivy-xkjmav?file=src/app/app.component.ts
