British media reports suggested this week that Bilic's fate could hinge on the results of West Ham's next two home games, with third-placed Liverpool set to visit the London Stadium a week after title-chasing Tottenham.
West Ham are not yet mathematically safe from relegation following an underwhelming season - they had one win in their past 11 league matches. That leaves them 15th in the table on 39 points with three games left.
"It's not the time to talk about my situation," Bilic told a news conference on Thursday. "It's the time to talk about the club. I'm very calm and focused on the game."
Off-field issues and the loss of playmaker Dimitri Payet to Olympique de Marseille in January have compounded West Ham's woes since leaving Upton Park for the London Stadium, but Bilic said his players were fired up by the prospect of facing Spurs.
"It's a massive London derby under the lights," he added. "On one hand, playing so many derbies is a disadvantage, but on the other, your players are more up for the games than for others."
While West Ham are still looking over their shoulder at the teams below them, Tottenham have their sights set on leaders Chelsea. They go into the game knowing a win will cut the gap at the top to a single point.
