I am remote too but in phase 2.
In the addendum to Connected Workplace 2.0, it says that "the company has the right to cancel remote work at any point, without any reason" (free translation). Dell incorporated sentences like that in work contract/addendum/internal regulations/etc. However, they are not in line with (most/all?) local European laws. Therefore, they are null and have no legal or binding force.
You signed a contract to work from home and it cannot be changed unilaterally by the employer. It's the same as your salary. It's the basic elements of the work contract. If you salary increases due to a bonus, you need to sign an addendum. If they want to decrease your salary for no reason, you need to sign an addendum too. If the company moves, you need to sign an addendum too. Also, if you are not at your official workplace (your home) and work inspection comes, you can get in trouble.
I'd advise you to search Irish local laws or ask any local HR/lawyer friend from another company to get their opinion on this. But I'm pretty sure it's like that for European phase 2 countries, otherwise we would be in phase 1.
