Yes, of course, in order to make the modifications I had to go to the \osticket\images folders and change the favicon images, including favicon 32x32 and 16x16, followed by going to the \assets\default\ folder images and replace the file poweredby.
Taking into account that not only the file must be modified, but also the dimensions of the file so that they can be seen correctly, the measurements of the files that are already found by default must be taken into account. With that I have managed to solve the problem of changing custom logos in the browser tabs.
