  As far as I know, there is no possibility to validate a collection directly, based on the properties you hand over to fields. But you could use a BeforeValidateHook to check whether a link has been provided or not. The only problem with this is that you have to make both of the fields optional and cannot directly show the user that the field is required (except you're using a custom component). But you could throw and error message using payloads ApiError to provide the user with context why it failed to save.

  I've created a simple example using a checkbox and a textfield:

  const Collection = {
    slug: 'my-collection',
    fields: [
      {
        name: "checkbox",
        type: "checkbox",
      },
      {
        type: "text",
        name: "text",
        required: false, // Important, else you won't be able to save
      },
    ],
    hooks: {
      beforeValidate: [
        ({ data }) => {
          if (data?.checkbox && data.checkbox === true) {
            // Make sure text has value
            if (!data.text || data?.text.trim() === "") {
              throw new APIError("Text is required");
            }
          }
        },
      ],
    },
  }

  Thank you for the APIError example. I'll use this for now!
