I'm not entirely sure. What is a tournament qualifier exactly?
Lasty night against Bangladesh was a qualifier for the 2026 WC.
https://en.wikipedia.org/wiki/FIFA_eligibility_rules
In September 2020, the 70th edition of the FIFA Congress approved a rule change that now allows players to switch if they have played no more than three competitive matches at senior level prior to them turning 21 including no appearances in FIFA World Cup finals matches or continental finals (e.g. the UEFA European Championship). However, appearing in a tournament qualifier would not prohibit a change of eligibility.[31][32][33][34] Furthermore, players who played for their home country but not at senior level, who were under 21 at the time and have since lived in a new country for five years or more can apply for the right to represent their new place of residence.[35] This also applies to players that began living on the territory before the age of 10 for at least three years.[36]

You would have to play more than 3 World cup qualifiers (or a mix between friendlies and qualifiers etc) to become cap tied.
I believe 1 World Cup match or continental finals (Euros, Copa America, OFC Nations Cup) appearance would cap tie you.
So from my interpretation of the rules, Irankunda would need another 3 friendlies or qualifiers to become cap tied.
