Can we access the logic used for generating, hashing, and validating the VerificationToken, used for Email magic link?

you can use to genarate generateVerificationToken tokens

pages/api/auth/[...nextauth].js

providers: [
  EmailProvider({
    async generateVerificationToken() {
      return "ABC123"
    }
  })
],

you can use sendVerificationRequest func in the EmailProvider to customize your logic

async function sendVerificationRequest(params) {
  const { identifier, url, provider, theme } = params
  const { host } = new URL(url)
  // NOTE: You are not required to use `nodemailer`, use whatever you want.
  const transport = createTransport(provider.server)
  const result = await transport.sendMail({
    to: identifier,
    from: provider.from,
    subject: `Sign in to ${host}`,
    text: text({ url, host }),
    html: html({ url, host, theme }),
  })
  const failed = result.rejected.concat(result.pending).filter(Boolean)
  if (failed.length) {
    throw new Error(`Email(s) (${failed.join(", ")}) could not be sent`)
  }
}
