I think it depends on "giant" definition.

Let's consider a planet 2 times Earth's size, identical density. Gravitation gets multiplier 8 due to volume => mass increase and 0.25 due to increased radius. So, it is 2g on surface.

Planet density can compensate for it to the some extent, e.g. Moon density is ~0.6 of Earth's. So, if planet density is 40% of Earth you get 0.8g on planet surface.

It gets worse as N grows, there certainly is a lower limit for density.

Planet twice larger than Earth has 4 times greater surface and if you get rid of oceans you can increase it ~4 times more.

Your planet can rotate really fast. Earth's gravity on equator is 0.3% lower due to centrifugal force. Planet can rotate much faster, Earth's rotation was slowed down by tidal locking with the Moon. If the planet rotates fast enough it will not be a sphere which would reduce gravitation near equator even more.
