You can find options for the project-wide design of tablature notation on the Tablature and Staves pages in Engraving Options.
The options on the Tablature page allow you to change the default direction, position, and alignment of stems, the position of rhythm dots, and the enclosures for chords on tablature. There are also options for tied notes. Many options are informed by the conventions established by different publishers.
On the Staves page, you can change the scale factor that controls the distance between tablature string lines.
There are musical examples for many options to demonstrate how they affect the appearance of your music.
