There has been slight acceleration compared to the 19th century, but it ended circa 1930. So it's not attributable to anthropogenic GHGs.

Their measurements show that there's been no significant acceleration in rate of sea-level rise in response to rising CO2 levels:

As you can see, there's been no significant acceleration in the rate of sea-level rise.

But it's so slight that In many places it's dwarfed by local factors, like erosion, sedimentation, and vertical land motion.
@GretaThunberg's town is one such place. There the land rises >3x as fast as the ocean.

Even there it's nearly negligible, for practical purposes. The trend was 0.0 mm/yr in 1800s, but +1.5 mm/yr since 1900 (six inches/century), & no significant acceleration since 1900 (only 0.00483±0.01121 mm/yr²).

It's been done accurately for >200 years, in some places.
It's not driven by AGW. CO2 levels have risen (rapidly) for 70 yrs. Temps have been rising (slowly) for 40 yrs. It has NOT measurably affected coastal sea-level trends.

But they all show the same lack of significant acceleration in response to rising CO2 levels:
