How do I disable the drag gesture on the navigation dots in a tabview to go between pages in SwiftUI?

Question

I use tabviews as stages for practices and I already disabled all swipe events to go between the tabs / stages. However, when you press and swipe or drag on the navigation dots you can still switch between the tabs. Preferably I would like to keep the navigation dots as a visual element, but disable any possibility of going between tabs. How can I achieve this?

This is the code for the view:

import SwiftUI

struct PracticeView: View {
    let practice : Practice
    @Environment(\.managedObjectContext) var viewContext
    @State var stageIndex = 0
    @State var practiceEnded = false
    private let dotAppearance = UIPageControl.appearance()
    
    
    var body: some View {
        let stages = practice.practiceStage.sorted(by: { $0.order < $1.order })
        
        VStack {
            
            Text(practice.wrappedTitle)
            
            TabView(selection: $stageIndex) {
                ForEach(stages) { stage in
                    VStack {
                        Spacer()
                        if stage.type == "Timer" {
                            TimerStageView(stageIndex : $stageIndex, stage: stage)
                        } else if stage.type == "Counter"{
                            CounterStageView(stageIndex : $stageIndex, stage: stage)
                        }

                        Spacer()
                    }
                    .frame(maxWidth: .infinity, maxHeight: .infinity)
                    .contentShape(Rectangle())
                    .gesture(DragGesture())
                    .tag(Int(stage.order))
                    .fullScreenCover(isPresented: $practiceEnded, content: FinishedView.init)
                }
            }
            .animation(.easeInOut, value: stageIndex)// 2
            .indexViewStyle(.page(backgroundDisplayMode: .interactive))
            .tabViewStyle(PageTabViewStyle(indexDisplayMode: .always))
            .highPriorityGesture(DragGesture())
        }
        .onAppear {
            dotAppearance.currentPageIndicatorTintColor = .black
            dotAppearance.pageIndicatorTintColor = .gray
        }
        .onChange(of: stageIndex) { value in
            if stageIndex == stages.count {
                practiceEnded = true
            }
            
        }
    }
    
}
