Ten + In, an invisible Ten shroud, is it possible through training?

I'm curious about the equivalent to Frieren's mana suppression in hunter hunter.

At first I'm thinking it's Ren + In as having a large pool of mana would require the large pool to be suppressed instead. But in terms of training, it doesn't seem possible if done by a regular nen user but seems possible if done by a master.

So I'm thinking in line for something smaller in scale; Ten + In instead, a training regimen to meditate and visualize the flow of the ten shroud, while hiding it's intentions and strength without losing the flow of aura but leaking the remaining 5% of the flow while hiding the rest of the ten shroud.

To advance progression the trainee should use gyo to be able to assess individual progression with the technique, to know how much aura is being hidden and how much aura was required to unveil the real aura output.

I'm trying to make this make sense for a trasmuter nen user with the need to hide their hatsu and strength by suppressing their Ten without losing its strength if that's even possible.

Think of like Gaara from Naruto. The nen user can have an invisible sand guard as their ten + ken and 80% enhancement to give it a solid feeling if the opponents come into contact within the users invisible ten, giving the impression of hitting concrete by hitting the user's face or body parts.

I'm still working on the overall hatsu but so far I have a general idea of how this user would operate and the personality and style for both combat and out of combat purposes.
