Hi! Just stop sending messages to it (i.e. don't call Update).

if spin {
	// Spin!
	var cmd tea.Cmd
	m.spinner, cmd = m.spinner.Update(msg)
	return m, cmd
} else {
	// Don't spin.
}

Here's an example where you can press s to start and stop the spinner:

package main

// A simple program demonstrating the spinner component from the Bubbles
// component library.

import (
	"fmt"
	"os"

	"github.com/charmbracelet/bubbles/spinner"
	tea "github.com/charmbracelet/bubbletea"
	"github.com/charmbracelet/lipgloss"
)

type errMsg error

type model struct {
	spinner  spinner.Model
	spin     bool
	quitting bool
	err      error
}

func initialModel() model {
	s := spinner.New()
	s.Spinner = spinner.Dot
	s.Style = lipgloss.NewStyle().Foreground(lipgloss.Color("205"))
	return model{
		spinner: s,
		spin:    true,
	}
}

func (m model) Init() tea.Cmd {
	return m.spinner.Tick
}

func (m model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
	switch msg := msg.(type) {

	case tea.KeyMsg:
		switch msg.String() {
		case "q", "esc", "ctrl+c":
			m.quitting = true
			return m, tea.Quit
		case "s":
			var cmd tea.Cmd
			m.spin = !m.spin // toggle the spinner
			if m.spin {
				cmd = m.spinner.Tick // restart the spinner
			}
			return m, cmd
		default:
			return m, nil
		}

	case errMsg:
		m.err = msg
		return m, nil

	case spinner.TickMsg:
		var cmd tea.Cmd
		// If m.spin is false, don't update on the spinner, effectively stopping it.
		if m.spin {
			m.spinner, cmd = m.spinner.Update(msg)
		}
		return m, cmd

	default:
		return m, nil
	}
}

func (m model) View() string {
	if m.err != nil {
		return m.err.Error()
	}
	str := fmt.Sprintf("\n\n   %s Loading forever...press s to toggle and q to quit\n\n", m.spinner.View())
	if m.quitting {
		return str + "\n"
	}
	return str
}

func main() {
	p := tea.NewProgram(initialModel())
	if err := p.Start(); err != nil {
		fmt.Println(err)
		os.Exit(1)
	}
}
