Is it possible to change the preloader animation on taskbar icons in KDE Plasma 5?

Question

KDE

Hello.
KDE Plasma 5.21
Kde framework 5.8

Is it possible to change preloader animation on taskbar icons in KDE Plasma 5?
When we launch a new application, then with a long launch, a preloader appears on the application icon in the taskbar - a rapidly spinning circle.
Is it possible to change the rotation speed or the entire animation?
Or completely disable this preloader?
