I found a way by creating lifecycles.js :
module.exports = {
async beforeUpdate(event) {
const { data, where } = event.params;
if (data.viewCount !== undefined) {
const entry = await strapi.entityService.findOne('api::game.game', where.id, { fields: ['updatedAt'] });
data.updatedAt = entry.updatedAt;
}
},
};
