[RESOLVED]

My final code:

const { ValidationError } = require('@strapi/utils').errors;

const validateSimpleModule = (event) => {
  const { params } = event;
  const { data } = params;
  // eslint-disable-next-line camelcase
  const { main_title, main_description, cta, subtitle } = data;

  // eslint-disable-next-line camelcase
  if (main_title && cta) {
    // eslint-disable-next-line camelcase
    if (!main_description) {
      throw new ValidationError(
        `Não é possível salvar o conteúdo dessa forma!`,
      );
    }
  }

  // eslint-disable-next-line camelcase
  if (main_title) {
    // eslint-disable-next-line camelcase
    if (!main_description || !cta || !subtitle) {
      throw new ValidationError(
        `Não é possível salvar o conteúdo dessa forma!`,
      );
    }
  }
};

module.exports = {
  async bootstrap({ strapi }) {
    // In order to resolve 502 problems in internal elb(between elb and target group), setting headers to 61 to 65 seconds.
    strapi.server.httpServer.keepAliveTimeout = 61 * 1000;
    strapi.server.httpServer.headersTimeout = 65 * 1000;

    // Listen lifecyles
    strapi.db.lifecycles.subscribe({
      models: ['simple-module.simple-module'], // listen only this model

      async beforeCreate(event) {
        validateSimpleModule(event);
      },

      async beforeUpdate(event) {
        validateSimpleModule(event);
      },
    });
  },
};
