The match in Sofia on Thursday, September 3, with kick-off at 7.45pm (Irish Time) will be Kenny's first match in charge of the national team ahead of a potential eight matches between now and November.
The Ireland squad landed in Sofia on Tuesday night and trained at the Vasil Levski Stadium this evening ahead of match day tomorrow.
Despite the short period of time Kenny has had to work with the Ireland squad, he has stressed the importance of playing for Ireland and has encouraged his players to display their talents.
"You've got to have values and you've got to stand for something, and I think that's important in the way the team will evolve," said Kenny.
"Always having that desire to play for Ireland and the realising the importance of playing for Ireland. I always want my team to have confidence in possession and also to want to show the full array of your talents.
"The last couple of days, we've been working on how we're going to play. It's been a really short time and it had to be modified as players played pre-season friendlies at the weekend.
"So, these games against Bulgaria and Finland are important to us because every international game for Ireland is important."
Ireland go into their Group Four match tomorrow evening looking to start their campaign on a positive note before Sunday's fixture in Dublin against Finland.
The UEFA Nations League represents a chance of 2022 World Cup qualification and this is a fact that isn't lost on Ireland manager Stephen Kenny.
"The winners of the group also have a chance, a good chance, of a World Cup play-off and we can't dismiss that. It's a tough group, with Wales as well, and there is a lot of football to be played, six matches, and then the Euro play-offs. It's a challenge but it's a challenge we're going to embrace," continued Kenny.
"We've only had two days. It would be great to have a good start. Bulgaria have had a couple of good results recently, beating the Czech Republic in the Euro qualifiers.
"Since their new coach has come in, they've played well so anything we get in Sofia, we'll have to earn."
