No way to control it separately from the axes.

You can disable the grid and draw the lines manually using the positions of the ticks.

is it possible to change length of ticks with TickLength and use them as grids?

You'll get black straight lines.

There is a new feature in R2023a for changing the grid line width. For more information, see this solution: https://www.mathworks.com/matlabcentral/answers/157863-change-grid-line-width

You can use 'GridAlpha' (initially set to 0.15). It has a similar effect as changing the LineWidth.

set(gca,'LineWidth',LineWidth)
...will set both the axes outline and grid line width.
