While cleaning my time trial bike I've noticed many scratches in the frame. See pictures below.
My tire pressure is usually around 100 psi, depending on the weather conditions or circuit. My wheels are the following: https://9thwave-cycling.com/product/road-sl50-wheels/
Should I be concerned? What can I do?
Thanks in advance.

Did you ride the bike in the rain? With tight tolerances the extra width added by the water can act like sandpaper if the water is also picking up fine sand or dirt.

Looks like you have had significant tire rub on the frame for a while. I'm surprised you did not notice the friction and drag.
If the abrasion is not all the way through the paint (the worst seems to be into the light colored primer) then you are probably OK in terms of physical damage. I might still be concerned about the possibility of heat damage, but if there does not seem to be heat damage to the paint the CFC epoxy is probably OK.
Presumably the bike did not always suffer from tire rub. Did you change to a wider tire? Have the dropouts been damaged? Looking at this image of a P2 on Cervelo's website I'd say there is something significantly amiss that has let the wheel shift forward.

Thank you for the answer. I have not changed the tires and the dropouts are fine.

@antao Something is wrong, check the image I linked to in updated answer. In that pic the curved seat-tube follows the circumference of the tire. Your wheel has evidently shifted forward somehow.

That's definitely tire rub. That frame has horizontal drop-outs to allow you to adjust the forward-back position of the wheel. When you take the wheel out, look in the dropout and you should see screws in there. I found a photo on the slowtwitch forum. Back them out a bit and then do another test fit. Make sure that the skewer is properly tightened too so that the wheel doesn't slip forward under load.
As far as the existing damage, I would recommend getting a reputable local bike shop to take a look at it because it's very hard to tell just from the photos, but it LOOKS like the damage is just to the paint and possibly the superficial outer layer of carbon. Again, get an LBS to inspect it to be safe. If it's just cosmetic as I suspect, you can seal it with a clear coat of some kind. Clear nail polish works surprisingly well.
