Hiding chevron from list, SwiftUI

Since ZStack stacks views on top of each other you can take advantage of that! Place a Text view on top of NavigationLink and replace Text view in the body of NavigationLink with an EmptyView

List(items, id: \.self) { item in
    ZStack(alignment: .leading) {
        Text(item.name)
        NavigationLink(destination: Text(item.name)) {
            EmptyView()
        }
        .opacity(0.0)
    }
} 

Here is a way to mimic a List without chevron, with a ScrollView:

            ScrollView(.vertical, showsIndicators: true)  {
                ForEach(0..<15) { index in
                    HStack {
                        Spacer()

                        NavigationLink(destination: DestinationView(item: index)) {
                            Text("Navigate \(index) to View 1")
                        }
                        // Text(">") // This would mimic a List's chevron                        
                        Spacer()

                    }
                    .padding(.vertical, 5)
                }
            }
            .navigationBarTitle("Navigation Links")
        }
    }
}

struct DestinationView: View {
    var item: Int

    var body: some View {
        Text("Destination View for item \(item)")
            .navigationBarTitle("View", displayMode: .inline)
    }
}

                ForEach (patients) { patient in
                     NavigationLink (value: patient) {
                   PatientRow(patient: patient)
                     }
                }
                .onDelete(perform: deletePatient)
                .listRowSeparator(.hidden)
            }
            .listStyle(.plain)
            .buttonStyle(PlainButtonStyle())
            .scrollIndicators(.hidden)
            .navigationDestination(for: Patient.self) { patient in
                PatientDetails(patient: patient)
            }

Above the foreach there's a line of code "List {" don't know why Apple editor cut it, the code formatting is very bad by the way.
