Please, Can I send an apdu to set the card read only to prevent data deletion?

You can change the authentication keys to achieve your goal and be sure to save the new key in secret.

For APDU command to change the authentication keys, check the GP specification.

Hi horse dream! Thanks for your answer.

I would like to put all the card as read-only without using an authentication key, is it possible?

Cheers,

You can also set your own PIN to fit your needs.

You can do some authentication, GP auth PIN auth, if authed, card can be modified, otherwise, the card content is read only. as "horse dream" said.
