Do you mean the license file (JSON)? I don't quite follow what an "access token" is in this context.
A "basic" license and a "trial" license are very different.
See Subscriptions | Elastic Stack Products & Support | Elastic for the feature breakdown.
A "basic" license is free, does not have security, and in more recent versions is a non-expiring license.
A "trial" license is typically available for 30 days, and does support security (but in more recent versions, trial licenses default to have security turned off, and it needs to be explicitly turned on again).
I'm not sure which license type you have, and what license you want, but if security is enabled then it's probably a trial (and you're probably on an older version of Elasticsearch).
I already explicitly added to disable xpack security on the elasticsearch.yml file
From your screenshot, it doesn't look like you have done that.
Lines that start with # are comments and are ignored.
#xpack.security.enabled: false
is not the same as
xpack.security.enabled: false

Is it possible to connect my Kibana instance to the Elastic.io (cloud)
We are not elastic.io - did you mean that URL, or found.io (which is us) ?
It is possible to connect your own Kibana instance to your Elastic Cloud Elasticsearch service, but ...
I don't understand what you mean here. Are you running Elasticsearch locally, or in our cloud?
And if you have a cloud instance, but don't have access to it, then you cannot connect Kibana to it.
