What value of capacitors should be unsoldered at the mSata connector on the motherboard (PCB) of the laptop?

What capacity should smd-capacitors be used in the binding of the mSata connector (at the break of the RXN, RXP, TXN, TXP tracks) on the board of the Asus x402ca laptop (or, possibly, any other)?
What capacity and allowable voltage should an smd capacitor be used between the +3.3V and GND pins of the tracks leading to the mSata connector?
Is it possible to use not smd, but ordinary capacitors (for example, the required value of ceramic capacitors used in amateur radio) and will their long / short legs interfere?

Well, they are standing next to each other, put the same ones.

1. In the lines RXN, RXP, TXN, TXP, capacitors with a capacitance of 10 nF (10 nF) are placed according to the SATA standard. The size is determined by the footprint on the board, but most often it is 0402. Voltage 6.3 V and higher. In this case, I highly do not recommend conclusions, because. I can’t imagine how to solder them so as not to worsen the line parameters.
2. There are nuances in nutrition, but in general it is something like 0.01uF, 0.1uF, 10uF in parallel. Enough 0.1uF and 10uF in parallel. Again, chip capacitors are better, because. although outputs can be soldered, they are easy to rip off by tearing something on the board. Plus, will they interfere with assembly?
Component ratings can be viewed on the diagrams of laptops with an msata connector. For example, Compal LA-6884P (I have one at home, the circuit is available).
There is no open access diagram for your laptop (because it is ASUS), but you can download the so-called. boardview - layout of components on the board. Search for "Asus x402ca boardview". It is convenient to view the file using the BoardViewer program from boardviewer.net
